Answer:

[tex]\large\boxed{M_{CD}\left(\dfrac{1}{2},\ -\dfrac{5}{2}\right)}[/tex]

Step-by-step explanation:

The formula of a midpoint of a segment AB with endpoints at A(x₁, y₁) and B(x₂, y₂):

[tex]M_{AB}\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)[/tex]

We have the points C(-3, -4) and D(4, -1).

Substitute:

[tex]M_{CD}(x,\ y)\\\\x=\dfrac{-3+4}{2}=\dfrac{1}{2}\\\\y=\dfrac{-4+(-1)}{2}=\dfrac{-5}{2}=-\dfrac{5}{2}[/tex]
