The Distance Formula (page 1 of 2). The Distance Formula is a variant of the Pythagorean Theorem that you used back in geometry. Here's how we get from the one to the other: Suppose you're given the two points (2, 1) and (1, 5) , and they want you to find out how far apart they are.The points look like this:he length of the hypotenuse is the distance between the two points. Since this format always works, it can be turned into a formula: Distance Formula: Given the two points (x1, y1) and (x2, y2) , the distance between these points is given by the formula: Don't let the subscripts scare you.
