How do you find the midpoint of (–3, 6) and (3, –6)?

Midpoint Formula

The midpoint $M$ of the points $\left({x}_{1} , {y}_{1}\right)$ and $\left({x}_{2} , {y}_{2}\right)$ can be found by

$M = \left(\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}\right)$

Let $\left({x}_{1} , {y}_{1}\right) = \left(- 3 , 6\right)$ and $\left({x}_{2} , {y}_{2}\right) = \left(3 , - 6\right)$.

By Midpoint Formula above,

$M = \left(\frac{- 3 + 3}{2} , \frac{6 + \left(- 6\right)}{2}\right) = \left(0 , 0\right)$

I hope that this was helpful.
