Question

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

Explanation:

Step1: Identify coordinates of H and K

The coordinate of H is 2 and the coordinate of K is 8.

Step2: Apply mid - point formula

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

Step3: Calculate the mid - point

$\frac{2+8}{2}=\frac{10}{2}=5$.
