To find the coordinate of the midpoint of $\overline{AB}$ .

Answer to Problem 1MRE

The midpoint of $\overline{AB}$ is $-2$ .

Explanation of Solution

Given information:On a number line, point A has coordinate $-11$ and B has coordinate $7$ .

Calculation:The required midpoint of $\overline{AB}$ is obtained as,

Let, M is the midpoint of AB.

  $M=\frac{-11+7}{2}=-2$

Hence, the midpoint of $\overline{AB}$ is $-2$ .
