Use the distance formula and a calculator to find the distance between two points. The distance formula works because if two points are plotted on a graph, their direct line is the hypotenuse of a right triangle; thus, the Pythagorean theorem can be used to determine the distance.Continue Reading
Each point has both an x and a y coordinate.
Subtract the x of point one from the x of point two. Square the result. Subtract the y of point one from the y of point two. Square that result too.
After squaring the distance between the x-coordinates and the y-coordinates, add the squared results together.
After the squared results are added together, take the square root of their sum. The result is the distance between the two points.
