Answer

$\left( \dfrac{-15}{2},-6 \right)$

Work Step by Step

Using the Midpoint Formula, $\left( \dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2} \right)$, then the midpoint between the given points is \begin{array}{l} \left( \dfrac{-6+(-9)}{2},\dfrac{-5-7}{2} \right) \\\\= \left( \dfrac{-15}{2},\dfrac{-12}{2} \right) \\\\= \left( \dfrac{-15}{2},-6 \right) .\end{array}
