Answer

$(-5, 2.5)$

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: $\text{midpoint}=\left(\frac{-2+(-8)}{2}, \frac{-1+6}{2}\right)=\left(\frac{-10}{2}, \frac{5}{2}\right)=(-5, 2.5)$
