Question

With
54

gallons of fuel in its tank, the airplane has a weight of
2329.4

pounds. What is the weight of the plane with
26

gallons of fuel in its tank?

Answer 1

y - 2418.6 = 5.9(x - 54)
y - 2418.6 = 5.9x - 318.6
y = 5.9x + 2100 
f(x) = 5.9x + 2100 (this is our function)
.
Now we can answer:
What is the weight of the plane with 26 gallons of fuel in its tank? 
f(26) = 5.9(26) + 2100 = 2253.4 pounds
