A coordinate plane of quadrant 1 is titled Mountain Bike Rental. The x-axis labeled Hours Rented ranges from 0 to 5 in increments of 1. The y-axis labeled Total Paid ranges from 20 to 30 in increments of 2. Six points plotted in the plane have the following coordinates: left parenthesis 0 comma 20 right parenthesis, left parenthesis 1 comma 22 right parenthesis, left parenthesis 2 comma 24 right parenthesis, left parenthesis 3 comma 26 right parenthesis, left parenthesis 4 comma 28 right parenthesis, and left parenthesis 5 comma 30 right parenthesis.

A coordinate plane of quadrant 1 is titled Total Amount Paid versus Hours Worked. The x-axis labeled Hours Worked ranges from 2 to 6 in increments of 1. The y-axis labeled Total Paid ranges from 0 to 125 in increments of 25. Five points plotted on the plane have the following coordinates: left parenthesis 2 comma 25 right parenthesis, left parenthesis 3 comma 50 right parenthesis, left parenthesis 4 comma 75 right parenthesis, left parenthesis 5 comma 100 right parenthesis, and left parenthesis 6 comma 125 right parenthesis.
What is the slope of the data?

To find the slope, we can use the formula:
Slope = (change in y) / (change in x)
Let's choose two points to calculate the slope. For example, let's use the points (2, 25) and (3, 50).
Slope = (50 - 25) / (3 - 2) = 25 / 1 = 25
Therefore, the slope of the data is 25.
Your company asked you to analyze the investment of their advertising campaign. You create a scatterplot graph of the advertising dollars spent on advertising, x, and compare it to the revenue generated, y, for January to December of the campaign. You find the equation of the trend line to be y=2.53x+43. Predict the revenue generated if your company invests $200.00 in advertising. Write the revenue in dollars and cents.(1 point)
The revenue generated for a $200.00 investment in advertising is ________ $
.
To predict the revenue generated if the company invests $200.00 in advertising, we can use the equation provided:
y = 2.53x + 43
where x = $200.00
Plugging in x = 200 into the equation:
y = 2.53(200) + 43
y = 506 + 43
y = $549.00
Therefore, the revenue generated if the company invests $200.00 in advertising is $549.00.
You work for a manufacturing company on a production line that manufactures cell phones. You are paid $30 a day plus $0.75 for each phone that you assemble. Predict your wages if you assemble 100 phone in one day, using the equation of the trend line y=0.75x+30 , where x is the number of phones assembled in one day and y is the total wages. Write your wages in dollars and cents.(1 point)
Your wages are $
.
To predict your wages when assembling 100 phones in one day, we need to use the equation provided:
y = 0.75x + 30
where x = 100 (number of phones assembled)
Plugging in x = 100 into the equation:
y = 0.75(100) + 30
y = 75 + 30
y = $105.00
Therefore, your wages for assembling 100 phones in one day would be $105.00.
