Question

which function is used to find y, the remaining balance after x number of payments have been made?

Answer 1

Given data:

The first point on the graph is (0,20,000).

The second point on the graph is (40,0).

The equattion of the line is,

(y-20,000)/(x-0)=(0-20,000)/(40-0)

(y-20,000)/(x)=-500

y-20,000=-500x

y=-500x+20,000

Thus, the equation of the line is y=-500x+20,000
