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 } = ( 120 - 60)/( 4 - 2) = ( 60)/( 2) =\boxed{\bf{ 30}}`

The rise over run of the graph shown is 30.
