Question

use the number line to find the coordinate of the midpoint of $overline{el}$.

Explanation:

Step1: Identify endpoint coordinates

The coordinate of point $E$ is $- 6$ and the coordinate of point $L$ is $10$.

Step2: Apply mid - point formula

The mid - point formula for two points with coordinates $x_1$ and $x_2$ on a number line is $\frac{x_1 + x_2}{2}$. Here $x_1=-6$ and $x_2 = 10$, so the mid - point $M=\frac{-6 + 10}{2}$.

Step3: Calculate the value

$\frac{-6+10}{2}=\frac{4}{2}=2$.

Answer:

$2$
