Explanation:

Step1: Recall mid - point formula

The mid - point formula for two points $(x_1,y_1)$ and $(x_2,y_2)$ is $(\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$. Here $x_1=-5,y_1 = - 4,x_2=-2,y_2=-8$.

Step2: Calculate x - coordinate of mid - point

$x=\frac{-5+( - 2)}{2}=\frac{-5 - 2}{2}=-\frac{7}{2}=-3.5$.

Step3: Calculate y - coordinate of mid - point

$y=\frac{-4+( - 8)}{2}=\frac{-4 - 8}{2}=\frac{-12}{2}=-6$.

Answer:

$(-3.5,-6)$
