The line equation is typically represented as


\begin{gathered} y=mx+b \\ \text{where} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}

Therefore,


\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(-2-4)/(4+4)=(-6)/(8)=-(3)/(4) \end{gathered}

Let find b


\begin{gathered} y=mx+b \\ 4=-(3)/(4)(-4)+b \\ b=1 \end{gathered}

The linear equation is


y=-(3)/(4)x+1
