Question

what is the distance between 0 and 4 on the number line? 4 units what is the distance between -4 and 0 on the number line? units use positive numbers to describe the distance between two points.

Explanation:

Step1: Recall distance formula on number - line

The distance between two numbers $a$ and $b$ on the number - line is given by $|a - b|$.

Step2: Calculate distance between - 4 and 0

Let $a=-4$ and $b = 0$. Then the distance $d=| - 4-0|=| - 4| = 4$.

Answer:

4
