Question

what is one way to find the distance? find $-15 - 7$. then take the absolute value. subtract. $-15 - 7 = -22$ what is the distance between $-15$ and $7$? units

Explanation:

Step1: Recall distance formula on number line

The distance between two numbers \(a\) and \(b\) on a number line is \(|a - b|\) (or \(|b - a|\)). Here, \(a=-15\) and \(b = 7\), so we can use \(|-15 - 7|\) or \(|7-(-15)|\).

Step2: Calculate the absolute value

We found \(-15 - 7=-22\) in the previous step. Now, take the absolute value of \(-22\), which is \(|-22| = 22\).

Answer:

22
