Walk through deriving a general formula for the distance between two points. The distance between the points ( x 1, y 1) and ( x 2, y 2) is given by the following formula: ( x 2 − x 1) 2 + ( y 2 − y 1) 2. In this article, we're going to derive this formula!

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points.
What is the distance formula? The formula gives the distance between two points ( x 1, y 1) and ( x 2, y 2) on the coordinate plane: ( x 2 − x 1) 2 + ( y 2 − y 1) 2. It is derived from the Pythagorean theorem. ( x 1, y 1) ( x 2, y 2) x 1 x 2 y 1 y 2 x 2 − x 1 y 2 − y 1 ? Want to learn more about the distance formula? Check out this video.
Distance Formula. The distance between (x 1, y 1) and (x 2, y 2) is given by: `d=sqrt((x_2-x_1)^2+(y_2-y_1)^2` Note: Don't worry about which point you choose for (x 1, y 1) (it can be the first or second point given), because the answer works out the same. Interactive Graph - Distance Formula
The Distance Formula is a useful tool for calculating the distance between two points that can be arbitrarily represented as points [latex]A[/latex] [latex]\left( {{x_1},{y_1}} \right)[/latex] and [latex]B[/latex] [latex]\left( {{x_2},{y_2}} \right)[/latex] on the coordinate plane.
The Distance Formula: Given the two points (x1, y1) and (x2, y2), the distance d between these points is given by the formula: \small {d = \sqrt { (x_2 - x_1)^2 + (y_2 - y_1)^2\,\vphantom {\frac {0} {0}}}} d= (x2 −x1)2 +(y2 −y1)2 00. Don't let the subscripts scare you, by the way.
The distance formula (also known as the Euclidean distance formula) is an application of the Pythagorean theorem a^2+b^2=c^2 a2 + b2 = c2 in coordinate geometry. It will calculate the distance between two cartesian coordinates on a two-dimensional plane, or coordinate plane.
