Perpendicular Slope Verification
An architectural drafter is verifying that two structural walls on a digital blueprint are perpendicular. If the slopes of the lines representing these walls are and , and neither wall is vertical or horizontal, what specific numerical value must the product of their slopes () yield to confirm they intersect at a 90-degree angle?
