Answer:
top left choice
Step-by-step explanation:
A car going at a higher speed than a second car will travel more distance in the same amount of time.
Look at the graph. For example, imagine that each grid line on the x-axis is 1 hour. Look at the 5th grid line to the right of the origin. That would mean 5 hours into the trips.
Now imagine that each grid line on the y-axis is 10 miles.
For the low speed car, at 5 hours, it traveled 40 miles.
For the high speed car, it traveled 70 miles in the same 5 hours.
That makes the x-axis the independent variable representing time, and the y-axis the dependent variable representing position.
