Given the points below,


\begin{gathered} (x_1,y_1)=(7,-3) \\ (x_2,y_2)=(4,-8) \end{gathered}

The formula to find the equation of a straight line is given below as,


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

Substituting the variables into the formula of a straight line above,


\begin{gathered} (y-(-3))/(x-7)=(-8-(-3))/(4-7) \\ (y+3)/(x-7)=(-8+3)/(-3) \\ (y+3)/(x-7)=(-5)/(-3)=(5)/(3) \\ (y+3)/(x-7)=(5)/(3) \\ \text{Crossmultiply} \\ 3(y+3)=5(x-7) \\ 3y+9=5x-35 \\ 5x-3y=35+9 \\ 5x-3y=44 \end{gathered}

The standard form of a straight is given as Ax + By = C

Hence, the answer is 5x -3y = 44
