Find the equation of the line perpendicular to that passes through the point .  

Solve for so the equation is in form.

Subtract from both sides.

Divide both sides by .

The line perpendicular to the line in the problem has a slope that is the negative reciprocal of the slope of line.

The slope of the line perpendicular to  is 

Substitute the point from the problem into the equation with slope  and solve for .
