Question

The graph shows the distance a car traveled, y, in x hours:

A coordinate plane graph is shown. The x-axis is labeled time in hours, and the y-axis is labeled distance in miles. The line passes through the points 2 comma 80, and 3 comma 120.

What is the rise-over-run value for the relationship represented in the graph?

40
80
1 over 40
1 over 80

Answer 1

The answer would be 40

Answer 2

The correct option is 1.

Explanation:

It is given that the x-axis is labeled time in hours, and the y-axis is labeled distance in miles.

The line is passing though (2,80) and (3,120).

If a line passing through to points, then

`m=(Rise)/(Run)=(y_2-y_1)/(x_2-x_1)`

`m=(120-80)/(3-2)`

`m=(40)/(1)`

`m=40`

Therefore correct option is 1.
