Determine the distance of two points on a number line

The video tutorial explains how to plot points on a line graph and determine the distance between them. It covers the basics of plotting points, understanding positive and negative directions, and introduces the concept of finding distances algebraically using absolute values. The tutorial provides an example to illustrate the calculation of distance between two points on a line graph.
