Question

The graph represents the total cost of renting a car after driving x miles.

A line graph plots total cost in dollar against total cost of renting a car. A ascending line from the origin is observed.

What does the slope represent in the graph?

A.
the miles driven per dollar
B.
the total cost during the rental
C.
the cost per mile driven
D.
the total distance traveled during the rental

Answer 1

In the context of the graph you described, where the x-axis represents miles driven and the y-axis represents total cost, the slope of the line represents the change in total cost per unit of distance driven. This is typically the cost per mile.

Therefore, the correct answer is:

**C. the cost per mile driven**.
