Solve.A school has just purchased new computer equipment for 
The graph shows the depreciation of the equipment over 5 years. The point (0, 19,000) 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 4 years.
A. y = - 19,000x + 19,000; value after 4 years is $-57,000.00 B. y = 19,000x + 5; value after 4 years is $3,800.00 C. y = - 3800x + 19,000; value after 4 years is $3,800.00; D. y = 3800x - 19,000; value after 4 years is $3,800.00
