what is the length of $overline{ef}$?
Answer
Explanation:
Step1: Identify coordinates
The coordinate of point E is 0 and the coordinate of point F is 3.
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, (EF=\vert3 - 0\vert). (EF = 3)
