Answer

$(2,5)$

Work Step by Step

We are given that the midpoint $M$ of a line segment $PQ$ with endpoints ($x_{1}$,$y_{1}$) and ($x_{2}$,$y_{2}$) is equal to: $M=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$ Therefore, $M=(\frac{5+(-1)}{2},\frac{2+8}{2})=(\frac{5-1}{2},\frac{10}{2})=(\frac{4}{2},\frac{10}{2})=(2,5)$.
