What is the Distance Formula?

Back

The Distance Formula is used to determine the distance between two points in a coordinate plane. It is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

How do you calculate the distance between the points (3, 4) and (7, 1)?

Back

Using the Distance Formula: d = √((7 - 3)² + (1 - 4)²) = √(16 + 9) = √25 = 5.

How do you find the distance between points in a three-dimensional space?

Back

In three-dimensional space, the Distance Formula is extended to d = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²).
