Question

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

Explanation:

Step1: Identify coordinates

The coordinate of point $F$ is $- 2$ and the coordinate of point $K$ is $8$.

Step2: Apply mid - point formula

The mid - point formula for two points $x_1$ and $x_2$ on a number line is $\frac{x_1 + x_2}{2}$. Here $x_1=-2$ and $x_2 = 8$. So, $\frac{-2 + 8}{2}=\frac{6}{2}=3$.

Answer:

$3$
