M = (-4, -5)

Step-by-step explanation:

Given:

C = (-2, -10) and D = (-6, 0)

Required:

Midpoint M of segment CD.

Solution:

$M = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$

Where,

(-2, -10) = (x_1, y_1)

(-6, 0) = (x_2, y_2)

Plug in the values into the equation

$M = (\frac{-2 + (-6)}{2}, \frac{-10 + 0}{2})$

$M = (\frac{-8}{2}, \frac{-10}{2})$

M = (-4, -5)
