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 2 years.
A. y = 19,000x + 5; value after 2 years is $11,400.00 B. y = - 3800x + 19,000; value after 2 years is $11,400.00; C. y = 3800x - 19,000; value after 2 years is $11,400.00 D. y = - 19,000x + 19,000; value after 2 years is $-19,000.00
