Solve.
-The average value of a certain type of automobile was $\$ 15,840$ in 1995 and depreciated to $\$ 4620$ in $1999 .$ Let $\mathrm { y }$ be the average value of the automobile in the year $\mathrm { x }$ , where $\mathrm { x } = 0$ represents 1995 . Write a linear equation that models the value of the automobile in terms of the year $x$ .

A) $y = - 2805 x + 15,840$
B) $y = - 2805 x + 4620$
C) $y = - 2805 x - 6600$
D) $y = - \frac { 1 } { 2805 } x - 4620$
