The expression can be used to find the distance between point A and point B.
The expression is:
distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Where:
- (x₁, y₁) are the coordinates of point A
- (x₂, y₂) are the coordinates of point B
This formula is also known as the distance formula or the Euclidean distance formula. It is derived from the Pythagorean theorem and represents the length of the shortest path between two points in a Cartesian coordinate system.
