You can put this solution on YOUR website! The slopes of perpendicular lines are negative reciprocals of each other. The negative part of "negative reciprocals" means the reciprocals have opposite signs.
So to find a negative reciprocal of some number:
Write it as a fraction if it is not already a fraction. (Put integers over a 1.)
Flip your number upside down and change its sign,
So to find the negative reciprocal of 2/3...
1. It is already a fraction.
2. Flip it upside down and change the sign: -3/2
