Given the line: 4y = 5x - 8

The slope of the given line = 5/4

The slope of the perpendicular line = -4/5

The line passes through the point (-5, 4 )

So, the point-slope equation will be:


(y-4)=(-4)/(5)(x+5)

Convert the equation to the slope-intercept form

So,


\begin{gathered} y-4=-(4)/(5)x-(4)/(5)\cdot5 \\ y-4=-(4)/(5)x-4 \\ y=-(4)/(5)x-4+4 \\ \\ y=-(4)/(5)x \end{gathered}

So, the answer will be option A. y= −4/5 x
