Answer
$(1, 5\sqrt{5})$
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:
$\text{midpoint}
\\=\left(\dfrac{8+(-6)}{2}, \dfrac{3\sqrt{5}+7\sqrt{5}}{2}\right)
\\=\left(\dfrac{2}{2}, \dfrac{10\sqrt{5}}{2}\right)
\\=(1, 5\sqrt{5})$
