Put the given equation into slope-intercept form and determine the slope by inspection.
The slopes of two perpendicular lines are negative reciprocals. Calculate the negagtive reciprocal of the slope of the given line and then use this value, along with the coordinates of the given point in the Point-Slope form to derive the desired equation.
where are the coordinates of the given point and is the calculated slope.
