Solve.A school has just purchased new computer equipment for 
The graph shows the depreciation of the equipment over 5 years. The point (0, 16,000) 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 = 16,000x + 5; value after 4 years is $3200.00 B. y = - 16,000x + 16,000; value after 4 years is $-48,000.00 C. y = - 3200x + 16,000; value after 4 years is $3200.00; D. y = 3200x - 16,000; value after 4 years is $3200.00
