Solve the problem.A driver wants to gauge the fuel efficiency of her vehicle. She notices that traveling at an average speed of 30 mph results in a rating of 28 mpg, whereas at an average speed of 35 mph, her car rates 18 mpg. Assume that the relationship between average speed (mph) and gas mileage (mpg) is linear. (a) Find an equation to model the gas mileage, y, for an average speed of x mph. Write your answer in slope-intercept form. (b) Use your equation from part (a) to estimate the gas mileage, rounded to the nearest whole number, the driver would get if her average speed was 25 mph.
A. (a) y = - 2x + 32; (b) 18 mpg
B. (a) y = - 2x + 88; (b) 138 mpg
C. (a) y = 
x + 32; (b) 45 mpg
D. (a) y = 
x + 88; (b) 101 mpg
