Question

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


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

20
30
1/20
1/30

Answer 1

$\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 } = \frac{ 120 - 60}{ 4 - 2} = \frac{ 60}{ 2} =\boxed{\bf{ 30}}$

The rise over run of the graph shown is 30.
