Distance Between Two Points on a Coordinate Plane

Front

What is the formula to calculate the distance between two points (x1, y1) and (x2, y2) on a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

What do you do to find the distance between two points with the same x-coordinates?

Back

Subtract the absolute value of their y-coordinates.
