Answer:

graph D

Explanation:

You want to choose the graph with a y-intercept of 70 and an x-intercept of 140. Graph D matches that.

Comment on graph D

The horizontal scale is a bit weird in that the numbers don't correspond to hash marks on the horizontal axis. The hash mark between the numbers 120 and 160 will correspond to a distance of 140 ft. That is where the graph touches the horizontal axis, so that is one indication it is the graph you want.
