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
Note: The distance between two points a and b is |b - a| or |a - b|

Yes, and using this definition, we find:

$$\displaystyle \overline{KN}=|-3-3|=|-6|=6$$
