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

Answer:

The correct answer is 30

Step-by-step explanation:

Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.

The line passes through the points (2,60) and (4,120)

To find: The rise-over-run value for the relationship in the graph.

\begin{aligned}m &=\frac{R i s e}{R u n} \\&=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\&=\frac{120-60}{4-2} \\&=\frac{60}{2} \\&=30\end{aligned}

Thus, the rise-over-run value for the relationship represented in the graph is 30.
