First figure out the slope. How does a slope perpendicular to another look like?

I am a mom that is trying to figure out

anonymous · Answer

Well, a perpendicular slope is the negative reciprocal of the slope. So if the slope is 5, then the slope perpendicular to it is the negative of that, which is -5, and then the reciprocal which is -1/5
