To find the coodinates of the midpoint (x,y) we use the following formula:
[tex]\begin{gathered} x=\frac{x_1+x_2}{2} \\ y=\frac{y_1+y_2}{2} \end{gathered}[/tex]Susbtituting
[tex]\begin{gathered} x_1=-4 \\ x_2=4 \\ y_1=6 \\ y_2=-2 \end{gathered}[/tex]we get:
[tex]\begin{gathered} x=0 \\ y=2 \end{gathered}[/tex]Finally, the coordinates of the midpoint are (0,2).
