Answer
$(1.5, -6)$
Work Step by Step
RECALL:
The midpoint of the line segment whose endpoints are $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the midpoint formula:
$\text{midpoint}=\left(\dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2} \right)$
Use the formula above to obtain:
$\text{midpoint} = \left(\dfrac{-3+6}{2}, \dfrac{-4+(-8)}{2}\right)=\left(\dfrac{3}{2}, \dfrac{-12}{2}\right)=(1.5, -6)$
