Answer
$$(-1,-0.5)$$
Work Step by Step
The coordinates $(x_{m},y_{m})$ of the midpoint of the segment joining the points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ are given by
$$x_{m}=\frac{x_{1}+x_{2}}{2}$$ and $$y_{m}=\frac{y_{1}+y_{2}}{2}$$
Substitute $x_{1}=-4$, $y_{1}=4$, $x_{2}=2$ and $y_{2}=-5$
$$x_{m}=\frac{-4+2}{2}=-1$$ and $$y_{m}=\frac{4+(-5)}{2}=-0.5$$
