What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

If two points have the same x-coordinate, how do you find the distance between them?

Back

Subtract the y-coordinates and take the absolute value.

What does it mean if the distance between two points is zero?

Back

The two points are the same.

How does the distance change if you move a point vertically?

Back

The distance changes by the amount of vertical movement.
