7-18.

Time should be on the x-axis.

Rate is distance divided by time.

2.2 feet per second

Find the number of feet Amy would travel per second.
Is it larger than your answer for part (b)?

$\frac{75 feet}{30 seconds} = 2.5 \frac{feet}{second}$

If you are still confused about which line should be steeper, try plotting
a line on your graph from part (a) to represent Amy's rate of travel.
The line should pass through the point (0, 0) and have a slope of 2.5.
