also another question i have is find the slope of the line.
the answers are, 1/5, -1/3 -3, 5
idk how to show pictures so i will do my best to describe the line.
it starts at positive 4 on the y axis, and steeply decreases to inbetween pos 1 and 2 on the x-axis, but slightly closer to the 1 than 2, and goes on.
please answer
let's put two points in y = m x + b)
you gave me (0,4)
you gave me about (1.4 , 0)
now
m = slope = (Y2-Y1) / (X2-X1) = (0-4) / (1.4-0) = -4/1.4 = -2.9 approximately
well, -3 is one of your choices
ok, THANK YOU SO MUCH!!!
you really helped!
To find the slope of a line, you need to determine the change in the y-coordinate divided by the change in the x-coordinate between two points on the line. In this case, you mentioned that the line starts at positive 4 on the y-axis and decreases steeply to a point between positive 1 and 2 on the x-axis.
To find the slope, we need to identify two points on the line and calculate the change in y divided by the change in x between those two points.
Let's choose two points on the line:
Point A: (1, 3)
Point B: (2, 1)
To find the change in y, subtract the y-coordinate of Point A from the y-coordinate of Point B:
Change in y = 1 - 3 = -2
To find the change in x, subtract the x-coordinate of Point A from the x-coordinate of Point B:
Change in x = 2 - 1 = 1
Now, divide the change in y by the change in x to calculate the slope:
Slope = Change in y / Change in x = -2 / 1 = -2
Therefore, the slope of the line is -2.
Now, let's analyze the possible answers you provided:
1. 1/5
2. -1/3
3. -3
4. 5
Since we found that the slope of the line is -2, none of the given answers match the slope we calculated. Therefore, none of the provided answers of 1/5, -1/3, -3, and 5 are correct for the slope of the line in this case.
