Start with the given equation.
Subtract from both sides.
Divide both sides by to isolate .
Simplify.
So the equation is now in slope intercept form where the slope is or . So the perpendicular slope is the negative reciprocal of . In other words, flip to get . Now change the sign to get
So the perpendicular slope is
