How to Find the Midpoint of Two Complex Numbers

From the graph you find that the endpoints of the line segment are $z=-2-i$ and $w=4+3i$. By using the endpoints you can calculate the midpoint:

$$\begin{array}{llll}\hfill m& =\frac{z+w}{2}& \hfill & \\ \hfill & =\frac{\left(-2-i\right)+\left(4+3i\right)}{2}& \hfill & \\ \hfill & =\frac{\left(-2+4\right)+\left(-1+3\right)i}{2}& \hfill & \\ \hfill & =\frac{2+2i}{2}& \hfill & \\ \hfill & =1+i.& \hfill & \end{array}$$
