Answer
$(-4, -5)$
Work Step by Step
RECALL:
The midpoint of $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the midpoint formula
$\text{midpoint}=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$
Use the formula above to obtain:
$\text{midpoint}=\left(\frac{-2+(-6)}{2}, \frac{-8+(-2)}{2}\right)=\left(\frac{-8}{2}, \frac{-10}{2}\right)=(-4, -5)$
