Answer
The midpoint of $\overline{AB}$ is $(5, \frac{7}{2})$.
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 $(6, 8)$ 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 $(5, \frac{7}{2})$.
