-1/2

right?

OpenStudy (anonymous):

Right, the negative reciprocal

OpenStudy (anonymous):

The definition of "perpendicular slope" is that the new slope perpendicular to the original slope will be the negative reciprocal of it. For example, if the original slope is 2/3, then the slope perpendicular to it will be -3/2. With that said, what is the negative reciprocal of 2?
