Question 1065176: suppose that the weight in pounds of an airplane is a linear function of the amount of fuel in gallons of this tank. when carrying 18 gallons of fuel, the airplane weighs 2117 pounds. when carrying 50 gallons of fuel, it weighs 2325 pounds. how much does the airplane weigh if it is carrying 54 gallons of fuel? How do you find the 2 coordinates for this equation?

x, gallons of fuel
y, weight of airplane
Points (x,y) from the description are (18, 2117) and (50, 2325).
Find equation of the line containing the two points.
slope .
If put into point slope equation form and pick point (18, 2117), then
.
