The point (0, 20,000) represents the purchase price and the point (5, 0) represents when the equipment will be replaced. Write a linear equation in slope-intercept form that models the value of the equipment, y, x years after purchase. Use the model to predict the value of the equipment after 3 years?

Question

A. y = - 20,000x + 20,000;
value after 3 years is $-40,000.00
B. y = 4000x - 20,000;
value after 3 years is $8000.00
C. y = 20,000x + 5;
value after 3 years is $8000.00
D. y = - 4000x + 20,000;
value after 3 years is $8000.00;
