If two points on a vertical line have coordinates (7, 2) and (7, 9), what is the distance between them?

Explanation:
When two points share the same x-coordinate, the distance between them is just the difference in their y-coordinates. Here the y-values are 2 and 9, so the distance is |9 − 2| = 7 units. The correct choice is the one that shows 7. The other numbers would correspond to other possible differences in y-values (5, 12, or 2), but they don’t match these two points.
