The cost of driving a car includes both fixed costs and mileage costs. Assume that it costs $162.80 per month for insurance and car payment and .31 ents a mile for oil, gasoline, and routine maintenance. Find values for m and b so that y=mx+b models the monthly cost of driving the car x miles. And what does the value of b represent?
