Question 286456: 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 6.4.
With 52 gallons of fuel in its tank, the airplane has a weight of 2432.8 pounds. What is the weight of the plane with 21 gallons of fuel in its tank?

y=6.4x+b
2432.8=6.4*52+b
b=2100
y=6.4x+2100
y=6.4*21+2100
y=2234.4
