Solve the problem.The gas mileage, m, of a compact car is a linear function of the speed, s, at which the car is driven, for 
For example, from the graph we see that the gas mileage for the compact car is 45 miles per gallon if the car is driven at a speed of 
The linear function M = -
s + 65 relates gas mileage, M, to speed, s.
Interpret the slope.
A. Between speeds of 40 and 90 mph, speed decreases at a rate of 0.5 miles per hour for each 1 mpg increase in gas mileage.
B. When the car is not moving, the gas mileage is 65 miles per gallon.
C. Between speeds of 40 and 90 mph, gas mileage decreases at a rate of 0.5 miles per gallon for each 1 mph increase in speed.
D. Between speeds of 40 and 90 mph, gas mileage increases at a rate of 0.5 miles per gallon for each 1 mph increase in speed.
