to find the center, we need to find the midpoint between these two points, the equation is:
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]so in this case:
[tex]\begin{gathered} (\frac{-10+5}{2},\frac{10-8}{2}) \\ (\frac{-5}{2},1)\text{ or (-2.5,1)} \end{gathered}[/tex]so the answer is: the center is in (-2.5,1)
