Answer :

The midpoint formula

[tex](x_{\frac{1}{2}},y_{\frac{1}{2}})=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2_{}})[/tex]

then, apply the formula

[tex]\begin{gathered} (x_{\frac{1}{2}},y_{\frac{1}{2}})=(\frac{-4+1}{2},\frac{-4+2}{2}) \\ (x_{\frac{1}{2}},y_{\frac{1}{2}})=(\frac{-3}{2},\frac{-2}{2}) \\ (x_{\frac{1}{2}},y_{\frac{1}{2}})=(\frac{-3}{2},-1) \end{gathered}[/tex]
