Let us plot the graph of value ($) against years

The general form for the linear equation is,


y=ax+b

where,


\begin{gathered} a=-4457.14 \\ b=38809.5 \end{gathered}

Hence, the equation that fits the data is


y=-4457.14x+38809.5

Let us now solve for the trailer's value in 7 years.


\begin{gathered} x=7 \\ \therefore y=-4457.14(7)+38809.5=7609.52\approx7609.50(1\text{ decimal place)} \\ \therefore y_(7yrs)=\text{ \$}7609.50 \end{gathered}

Hence, the answer is


y_(7yrs)=\text{ \$}7609.50\text{ (OPTION }3)
