$\left( -\dfrac{9}{2}, \dfrac{3}{2} \right)$

Work Step by Step

$\bf{\text{Solution Outline:}}$ Use the Midpoint Formula to find the midpoint of the line segment joining the given points, $( 0,-5 )$ and $( -9,8 ).$ $\bf{\text{Solution Details:}}$ Using $\left( \dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2} \right)$ or the Midpoint Formula, then the midpoint of the line segment with the endpoints given above is \begin{array}{l}\require{cancel} \left( \dfrac{0+(-9)}{2}, \dfrac{-5+8}{2} \right) \\\\= \left( \dfrac{0-9}{2}, \dfrac{-5+8}{2} \right) \\\\= \left( \dfrac{-9}{2}, \dfrac{3}{2} \right) \\\\= \left( -\dfrac{9}{2}, \dfrac{3}{2} \right) .\end{array}
