Question

On a number line, point Ahas a coordinate -5and B has 3. Find the coordinate of the midpoint of$\overline{AB}$.

Short answer

The coordinate of the midpoint is$-1$.

Step-by-step solution

Step 1- Apply the concept of coordinate of midpoint.

For any line segment, the midpoint is halfway between its two endpoints. It can be calculated by taking average of the endpoints.

Step 2- Find the coordinate.

Find the coordinate of the midpoint is as follows:

$\begin{array}{c}\text{midpointof}\overline{AB}=\frac{-5+3}{2}\\ =-\frac{2}{2}\\ =-1\end{array}$

Step 3- Step description.

The coordinate of the midpoint of the segment is-1 .

Therefore, the coordinate is-1 .
