y

The absolute value of the difference of their coordinate (if it is in one dimension).
Because line segment lengths are often calculated as a square root, the absolute value symbols indicate it is only the positive solution that counts, as a distance cannot be negative.
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.

Add the x-coordinates of the points and take the absolute value
Subtract the y-coordinates of the points and take the absolute value
This is the length of the segment.
The definition for length of segment is the distance between the endpoints of s segment
