Solve.A school has just purchased new computer equipment for 
The graph shows the depreciation of the equipment over 5 years. The point (0, 23,000) 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 4 years?
A. y = - 23,000x + 23,000;
value after 4 years is $-69,000.00
B. y = 23,000x + 5;
value after 4 years is $4600.00
C. y = - 4600x + 23,000;
value after 4 years is $4600.00;
D. y = 4600x - 23,000;
value after 4 years is $4600.00
