What is the distance between the points (2, 5) and (2, 1)?

Explanation:
Two points that share the same x-coordinate lie on a vertical line, so the distance between them is just the difference in their y-values. Here, both points have x = 2, and their y-values are 5 and 1. The vertical distance is 5 − 1 = 4 (absolute value keeps it positive). So the distance is 4. If you use the distance formula, you’d get sqrt((2−2)^2 + (5−1)^2) = sqrt(0 + 16) = 4.
