Question

find the length of $overline{vw}$. v -31 w -13 vw = ?

Explanation:

Step1: Identify the formula

The length between two points on a number - line is given by \(|a - b|\), where \(a\) and \(b\) are the coordinates of the two points. Here, \(a=-13\) and \(b = - 31\).

Step2: Calculate the difference

\(|-13-(-31)|=|-13 + 31|\)

Step3: Simplify the expression

\(|-13 + 31|=|18|=18\)

Answer:

18
