Since your given equation is in standard form, divide the opposite of the coefficient on by the coefficient on to find the slope of the given line.

Perpendicular lines have negative reciprocal slopes, so take the negative reciprocal of the slope you just calculated. Then use the point-slope form:



where are the coordinates of the given point and is the calculated slope.
