Question Analysis

This question involves calculating the length of a line segment.

 

Key Concept Explanation

The length of a line segment between two points and on a number line is the absolute value of the difference between their coordinates. If the coordinate of point is and the coordinate of point is , then the length . Distance is always non - negative.

 

Step - by - Step Solution

1. Assume the coordinate of point is and the coordinate of point is .

2. Calculate the difference or
