Find the straight-line distance between two points on the coordinate plane.
Distance
5
Straight-line distance between the two points.
How it works
- 1Enter the coordinates of two points.
- 2The distance formula is √((x₂ − x₁)² + (y₂ − y₁)²).
- 3Read the straight-line distance between the points.
Use cases
- Find the length of a line segment.
- Measure the gap between two coordinates on a graph.
- Solve distance-formula homework.
Frequently asked questions
What is the distance formula?
It comes from the Pythagorean theorem: distance = √((x₂ − x₁)² + (y₂ − y₁)²).
Does the order of the points matter?
No. The differences are squared, so swapping the two points gives the same distance.
What units does it use?
Whatever units your coordinates are in — the distance comes out in the same units.
