We are interested in exploring the relationship between the weight of a vehicle and its fuel efficiency (gasoline mileage). The data in the table show the weights, in pounds, and fuel efficiency, measured in miles per gallon, for a sample of 12 vehicles.

Find the equation of the best fit line.

ŷ = _______    x + ________

Weight Fuel
Efficiency
2695 25
2510 26
2680 29
2770 38
3000 23
3410 24
3640 20

Facts: Your firm produces and leases vehicles while reimbursing customers for the cost of fuel of these vehicles. Each customer pays you $2,000 a year to operate a vehicle for ten years. Over the life of a vehicle, the customer drives 20 miles a day for 300 days a year for ten years before scrapping the vehicle (for 60,000 miles in total). The price of gas is now $2 a gallon. The steel vehicle consumes 0.04 gallons per mile (or...
