First get the equation in the form

where m is the slope, then the line perpendicular
to it will have slope =

subtract from both sides

divide both sides by

So the line perpendicular to the given line will look like

To find , plug (9, -5) into the equation

The answer is
check:
does it go through (9, -5)?

OK
