Question

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

Explanation:

Step1: Identify the coordinates of K and M

From the number line, the coordinate of \( K=-4 \) and the coordinate of \( M = 0 \).

Step2: Use the mid - point formula

The mid - point formula for two points \( x_1\) and \(x_2\) on a number line is \( \frac{x_1 + x_2}{2}\).
Substitute \(x_1=-4\) and \(x_2 = 0\) into the formula: \(\frac{-4+0}{2}\).

Step3: Calculate the mid - point

\(\frac{-4 + 0}{2}=\frac{-4}{2}=-2\)

Answer:

\(-2\)
