You can put this solution on YOUR website!
Given L%5B1%5D: y=m%5B1%5Dx%2Bb%5B1%5D and L%5B2%5D: y=m%5B2%5Dx%2Bb%5B2%5D, L%5B1%5D is perpendicular to L%5B2%5D if and only if m%5B1%5D=-1%2Fm%5B2%5D, which is to say that the slopes are the negative reciprocal of each other.

Given the angle measure between two intersecting lines: The two lines are perpendicular if and only if the angle measure is either 90 degrees or pi%2F2 radians.

That's 57 words, give or take.
