Question

use the number line to find np. np =

Explanation:

Step1: Identify coordinates

The coordinate of $N$ is 3 and the coordinate of $P$ is 5.

Step2: Calculate distance

The distance between two points on a number - line is given by the absolute value of the difference of their coordinates. So $NP=\vert5 - 3\vert$.

Step3: Simplify expression

$\vert5 - 3\vert=\vert2\vert = 2$.
