write an equation to show the relationship between x and y
To show the relationship between x (time) and y (distance), we can use the equation:
y = mx + b
where m represents the slope (rate of change), and b represents the y-intercept.
To find the slope, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Let's use the points (8, 664) and (5, 415) to calculate the slope:
m = (415 - 664) / (5 - 8) = -249 / -3 = 83
Now that we have the slope, we can substitute it into the equation:
y = 83x + b
To find the y-intercept (b), we can substitute the coordinates of any of the points into the equation. Let's use the point (8, 664):
664 = 83(8) + b
By solving this equation, we can find the value of b:
664 = 664 + b
b = 664 - 664
b = 0
Thus, the equation that represents the relationship between x and y is:
y = 83x
is the relationship proportional? what is the y intercept
Yes, the relationship between x (time) and y (distance) is proportional.
The y-intercept is the value of y when x is equal to zero. In this case, the equation representing the relationship between x and y is y = 83x. When x is zero, the equation becomes y = 83(0), which simplifies to y = 0.
Therefore, the y-intercept is 0.
5. A cab company charges $12 per mile for a lift to the airport. What change would the company make to their charges to make this a non proportional situation? (1 point) Responses Charge $4 per mile instead of $12 Charge $4 per mile instead of $12 No changes are needed. No changes are needed. Charge $15 per mile instead of $12 Charge $15 per mile instead of $12 Charge a flat rate of $20 and then $12 per mile
To make the situation non-proportional, the cab company could make the following change to their charges: Charge a flat rate of $20 and then $12 per mile. This means that there would be an initial flat fee of $20, regardless of the distance traveled, and then an additional charge of $12 for each mile traveled. This would make the relationship between the cost and distance non-proportional, as the cost would no longer be directly proportional to the number of miles.
6. One business charges $22 per t-shirt that is custom made. Another business charges $16 per t-shirt plus a $15 set up fee for custom made t-shirts. How would you transform the first graph to make it become a non proportional graph with the same y-intercept as the second graph? (1 point) Responses Left 15 Left 15 Up 4 Up 4 Down 4 Down 4 Right 4 Right 4 Up 15 Up 15 Down 15
To transform the first graph to make it become a non-proportional graph with the same y-intercept as the second graph, you would need to shift the graph up by 15 units.
This can be done by adding a constant value of 15 to each y-coordinate of the points on the graph. This transformation would create a new graph where the y-values are higher than they were in the original graph, creating a non-proportional relationship between the x-values and y-values with the same y-intercept as the second graph.
7. Solve this equation for y: 7y=12x (1 point) Responses y=12x+7 y is equal to 12 x plus 7 y=12x−7 y is equal to 12 x minus 7 y=712x y is equal to 7 over 12 x y=127x
To solve the equation 7y = 12x for y:
We first need to isolate y by dividing both sides of the equation by 7:
(7y)/7 = (12x)/7
Simplifying, we have:
y = (12/7)x
Thus, the solution to the equation is y = (12/7)x.
7. Solve this equation for y: 7y=12x (1 point) Responses y=12x+7 y is equal to 12 x plus 7 y=12x−7 y is equal to 12 x minus 7 y=7/12x y is equal to 7 over 12 x y=12/7x
To solve the equation 7y = 12x for y:
We can isolate y by dividing both sides of the equation by 7:
(7y) / 7 = (12x) / 7
Simplifying, we have:
y = (12/7)x
Thus, the solution to the equation is y = (12/7)x.

13. Suppose that the water level of a river is 45 feet after 3 days of no rain and 10 feet after 10 days of no rain. The river was 60 feet before the drought began.(4 points) Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. a. What is the rate of change (slope) for this scenario? Response area b. What is the y-intercept for this scenario? Response area c. Write an equation for the scenario in slope-intercept form. Response area d. Write an equation in standard form.
To find the rate of change (slope) for this scenario, we can use the formula:
slope = (change in y)/(change in x)
In this case, the change in y is 10 - 45 = -35 (the decrease in water level), and the change in x is 10 - 3 = 7 (the number of days).
Therefore, the slope is: slope = -35/7 = -5.
To find the y-intercept (b), we can use the given information that the river was initially 60 feet before the drought began.
Therefore, the y-intercept is 60.
Thus, the equation for the scenario in slope-intercept form is:
y = -5x + 60.
To write the equation in standard form, we can rearrange it by adding 5x to both sides:
5x + y = 60.
Therefore, the equation in standard form is:
5x + y = 60.
some of these are not answer choices, please provide the correct answers
Apologies for the confusion. Here are the correct answers:
a. The rate of change (slope) for this scenario is -5.
b. The y-intercept for this scenario is 60.
c. The equation for the scenario in slope-intercept form is y = -5x + 60.
d. The equation in standard form is 5x + y = 60.
is "the y intercept for this scenario" correct? it is not an answer choice
I apologize for the oversight. Let's correct the answer choices:
a. The rate of change (slope) for this scenario is -5.
b. This scenario does not have a y-intercept since the river was initially 60 feet before the drought began.
c. The equation for the scenario in slope-intercept form is y = -5x + 60.
d. The equation in standard form is 5x + y = 60.
14. Suppose that the water level of a river is 45 feet after 3 days of no rain and 10 feet after 10 days of no rain. Given the two points we know: (3, 45) and (10, 10), what would the point slope equation look like?(1 point) Responses (y−10)=−5(x+10) open paren y minus 10 close paren is equal to negative 5 times open paren x plus 10 close paren (y+10)=−5(x−10) open paren y plus 10 close
The point-slope equation using the two points (3, 45) and (10, 10) would look like:
(y - 10) = -5(x - 10)
So, the correct response is: (y - 10) = -5(x - 10)
what would a graph that matches the linear equation -2x+3y=-6 look like?
The graph of the linear equation -2x + 3y = -6 would be a straight line. To graph this equation, we can rearrange it and solve for y in terms of x:
-2x + 3y = -6
3y = 2x - 6
y = (2/3)x - 2
Now, we can plot the graph using the slope-intercept form y = mx + b, where the slope (m) is 2/3 and the y-intercept (b) is -2.
The graph would have a slope of 2/3, meaning for every 3 units of horizontal change (x), there will be 2 units of vertical change (y). The line would be downward sloping from left to right, crossing the y-axis at y = -2.
The graph would look like a straight line passing through the point (0, -2) and with a slope of 2/3.
are you correct/
Yes, the information provided is correct. The graph of the linear equation -2x + 3y = -6 would indeed be a straight line with a slope of 2/3 and crossing the y-axis at y = -2.
17. The tables below show the number of jumping jacks completed after a given period of time in seconds. Kimberly: Time (seconds) Jumping Jacks 3 17 8 37 12 53 16 69 Katrina: Time (seconds) Jumping Jacks 2 10 5 25 12 60 20 100(3 points) a. Which person is doing more jumping jacks per second? b. Which person had done more jumping jacks initially before the timer started? c. Which person shows a proportional relationship?
a. To determine who is doing more jumping jacks per second, we need to calculate the rate of jumping jacks per second for each person.
For Kimberly:
Rate = Number of jumping jacks / Time in seconds
Rate = 69 jumping jacks / 16 seconds
Rate ≈ 4.31 jumping jacks per second
For Katrina:
Rate = Number of jumping jacks / Time in seconds
Rate = 100 jumping jacks / 20 seconds
Rate = 5 jumping jacks per second
Therefore, Katrina is doing more jumping jacks per second compared to Kimberly.
b. To know who has done more jumping jacks initially before the timer started, we need to look at the number of jumping jacks at the smallest time given.
For Kimberly: 3 seconds, 17 jumping jacks
For Katrina: 2 seconds, 10 jumping jacks
Since Kimberly has done more jumping jacks initially with 17 compared to Katrina's 10, Kimberly had done more jumping jacks initially before the timer started.
c. To determine if there is a proportional relationship, we need to compare the ratios of jumping jacks completed to the time in seconds for both individuals.
Kimberly's Ratios:
17/3 ≈ 5.67 jumping jacks per second
37/8 ≈ 4.63 jumping jacks per second
53/12 ≈ 4.42 jumping jacks per second
69/16 ≈ 4.31 jumping jacks per second
Katrina's Ratios:
10/2 = 5 jumping jacks per second
25/5 = 5 jumping jacks per second
60/12 = 5 jumping jacks per second
100/20 = 5 jumping jacks per second
Both Kimberly and Katrina show a proportional relationship as the ratio of jumping jacks to time remains constant for each person.
