Distance Formula: Distance of Points

The distance formula is used to find the straight-line distance between two points on a coordinate plane. If the points are (x_1, y_1) and (x_2, y_2), the distance is found using d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} It comes from the Pythagorean theorem and measures the shortest path between the two coordinates.
