Step 1: Determine the slope of the line represented by the given equation. Since this equation is in slope-intercept form, namely , this is a simple matter of examining the coefficient on . Step 2: Calculate the negative reciprocal of the slope number you determined in Step 1. This is because perpendicular lines have slopes that are negative reciprocals: Step 3: Use the point-slope form of an equation of a line to write the desired equation: where are the coordinates of the given point and is the from Step 2. Depending on your instructor's or textbook's instructions, you may need to re-arrange your equation to put it into either slope-intercept form: Or Standard form John My calculator said it, I believe it, that settles it
