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 6.3. See the figure below.
with 49 gallons of fuel in its tank, the airplane has a welght of 2308.7 pounds. What is the weight of the plane with 16 gallons of fuel in its tank?
