Suppose that the weight (in pounds) of an airplane is a linear function of the total amount of fuel (In gallons) in its tank. When graphed, the function gives a line with a slope of 6.2. See the figure below.
with 49 gallons of fuel in its tank, the airplane has a weight of 2303.8 pounds. What is the welght of the plane with 18 gallons of fuel in its tank?
