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

Work Step by Step

With the given points, then \begin{array}{l}\require{cancel} x_1= -7 ,\\x_2= 3 ,\\y_1= -2 ,\\y_2= -1 .\end{array} 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{x_1+x_2}{2}, \dfrac{y_1+y_2}{2} \right) \\\\= \left( \dfrac{-7+3}{2}, \dfrac{-2+(-1)}{2} \right) \\\\= \left( \dfrac{-7+3}{2}, \dfrac{-2-1}{2} \right) \\\\= \left( \dfrac{4}{2}, \dfrac{-3}{2} \right) \\\\= \left( 2,-\dfrac{3}{2} \right) .\end{array}
