Question

what is the length of $overline{jk}$?

Explanation:

Step1: Identify coordinates

The coordinate of point J is 98 and the coordinate of point K is 99.

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, \(d=\vert99 - 98\vert\).
\(\vert99 - 98\vert=1\)
