Answer

The coordinates of the midpoint of $\overline{AB}$ are $(1, 1)$.

Work Step by Step

The midpoint of $\overline{AB}$ can be found using the following formula: $M = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$ The points we are given are $(7, 10)$ and $(-5, -8)$. Let's plug these points into the formula: $M = (\frac{7 + (-5)}{2}, \frac{10 + (-8)}{2})$ Use addition to simplify: $M = (\frac{2}{2}, \frac{2}{2})$ Simplify the fractions: $M = (1, 1)$ The coordinates of the midpoint of $\overline{AB}$ are $(1, 1)$.
