According to the given data we have the following points:
(-2,-4) (2,7)
In order to find the midpoint of (-2,-4) (2,7) we would use the following formula:
[tex]Midpoint=(\frac{xa+xb}{2},\frac{ya+yb}{2})[/tex][tex]\text{Midpoint}=(\frac{-2+2}{2},\frac{-4+7}{2})[/tex][tex]\begin{gathered} Midpoint=(\frac{0}{2},\frac{-3}{2}) \\ Midpoint=(0,-1.5) \end{gathered}[/tex]Therefore, the midpoint of (-2,-4) (2,7) would be (0,-1.5)
