Answer:
Midpoint = (-5,-7)
Step-by-step explanation:
[tex]Midpoint =\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-9,\:-5\right),\:\\\left(x_2,\:y_2\right)=\left(-1,\:-9\right)\\\\Midpoint=\left(\frac{-1-9}{2},\:\frac{-9-5}{2}\right)\\\\Midpoint = (\frac{-10}{2} , \frac{-14}{2})\\ \\Simplify\\\\Midpoint=\left(-5,\:-7\right)[/tex]
