The vertical segment joining A (1,5) and B (1,1) has been graphed on the number plane. Find the length of the segment.


  1. Answer:
    4 units
    Step-by-step explanation:
    because the points have the same x-coordinate, we just need to subtract the y-coordinates to find the distance.
    5 – 1 = 4
    therefore, the length of the segment is 4 units.
    hope this helps! <3
