Solve.A school has just purchased new computer equipment for 
The graph shows the depreciation of the equipment over 5 years. The point (0, 22,000) 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 relates the value of the equipment, y, to years after purchase x . Use the equation to predict the value of the equipment after 3 years.
A. y = - 22,000x + 22,000; value after 3 years is $-44,000.00 B. y = 22,000x + 5; value after 3 years is $8800.00 C. y = 4400x - 22,000; value after 3 years is $8800.00 D. y = - 4400x + 22,000; value after 3 years is $8800.00;
