Solution:

To find the equation of a line, the formula is


(y-y_1)/(x-x_1)=(y_2-y_1)/(x_2-x_1)

Where


\begin{gathered} (x_1,y_1)=(3,-2) \\ (x_2,y_2)=(-4,8) \end{gathered}

Substitute the values of the variable


\begin{gathered} (y-(-2))/(x-3)=(-8-(-2))/(-4-3) \\ (y+2)/(x-3)=(-8+2)/(-7) \\ (y+2)/(x-3)=(-6)/(-7) \end{gathered}
\begin{gathered} Crossmultiply \\ -7(y+2)=-6(x-3) \\ -7y-14=-6x+18 \\ 6x-7y-18-14=0 \\ 6x-7y-32=0 \end{gathered}

Hence, the equation is


6x-7y-32=0
