Question

Megan is going on a long distance road trip. She drives for 13 miles before being able to travel at a constant speed using cruise control. The equation used to find her total distance traveled is shown below.

y = 59x + 13


If y is the total number of miles driven, and x is the number of hours driven after reaching 13 miles, which statement best describes the rate of change in the distance traveled?

A. For every 13 hours, she will drive 72 miles.
B. For every two hours, she will drive 59 miles.
C. For every hour, she will drive 59 miles.
D. For every hour, she will drive 72 miles.

Answer 1

The rate of change of y (miles traveled) with respect to x (time in hours) is 59, the coefficient of x. The appropriate choice is ...

... C. For every hour, she will drive 59 miles.
