## Geometry: Common Core (15th Edition)

The midpoint of $\overline{AB}$ is $(5, \frac{7}{2})$.
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 $(6, 8)$ and $(4, -1)$. Let's plug these points into the formula: $M = (\frac{6 + 4}{2}, \frac{8 + (-1)}{2})$ Use addition to simplify: $M = (\frac{10}{2}, \frac{7}{2})$ $M = (5, \frac{7}{2})$ The midpoint of $\overline{AB}$ is $(5, \frac{7}{2})$.
