Question

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

Explanation:

Step1: Identify coordinates

The coordinate of $K$ is $- 4$ and the coordinate of $M$ is $0$.

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 $x_1=-4$ and $x_2 = 0$, so $\frac{-4 + 0}{2}=\frac{-4}{2}=-2$.

Answer:

$-2$
