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!
Quick Explanation. When we know the horizontal and vertical distances between two points we can calculate the straight line distance like this: distance = √ a2 + b2. Imagine you know the location of two points (A and B) like here. What is the distance between them? We can run lines down from A, and along from B, to make a Right Angled Triangle.

The blue graph (d (x)) represents the distance from the point (a,b) to the graph of f (x). Move (a,b) around to see the distances change; then move the point on the graph of d (x) to relative extrema to see the distance relationship. to save your graphs!
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. Created by Sal Khan and CK-12 Foundation.
