Use the number line to find the measure.
KN
Question options:= 6, 0, 3, 5
Suppose \(\displaystyle A~\&~B\) are points on a number line and if \(\displaystyle \mathcal{C}_A~\&~\mathcal{C}_B\) are the coordinates of those points then the distance \(\displaystyle AB=\left|\mathcal{C}_A - \mathcal{C}_B\right|\)

3 - (-3) = 6

Yes, and using this definition, we find:

\(\displaystyle \overline{KN}=|-3-3|=|-6|=6\)
