$\text{midpoint} =(-3, -2)$

Work Step by Step

RECALL: The midpoint of the line segment whose endpoints are $(x_1, y_1)$ and $(x_2, y_2)$ can be found using the midpoint formula: $\text{midpoint}=\left(\dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2} \right)$ Use the formula above to obtain: $\text{midpoint} = \left(\dfrac{-\frac{7}{2}+(-\frac{5}{2})}{2}, \dfrac{\frac{3}{2}+(-\frac{11}{2})}{2}\right)=\left(\dfrac{-\frac{12}{2}}{2}, \dfrac{-\frac{8}{2}}{2}\right) \\\text{midpoint} = \left(\dfrac{-6}{2}, -\dfrac{4}{2}\right)=(-3, -2)$
