Solve.
-A school has just purchased new computer equipment for $\$ 23,000.00$ . 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) $y = - 4600 x + 23,000$ ;
value after 4 years is $\$ 4600.00$ ;
B) $\mathrm { y } = 23,000 \mathrm { x } + 5$ ;
value after 4 years is $\$ 4600.00$
C) $\mathrm { y } = 4600 \mathrm { x } - 23,000$ ;
value after 4 years is $\$ 4600.00$
D) $y = - 23,000 x + 23,000$ ;
value after 4 years is $\$ - 69,000.00$
