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 
Find the average rate of change in gas mileage between speeds of 40 mph and 60 mph. Find the average rate of change in gas mileage between speeds of 50 mph and 70 mph. Find the
average rate of change in gas mileage between speeds of 70 mph and 90 mph. Based on your results, do you think that gas mileage is linearly related to speed? Explain.
What will be an ideal response?
-0.5 miles per gallon/mph; -0.5 miles per gallon/mph; -0.5 miles per gallon/mph;
Yes, the average rate of change (slope) is constant.
