Distance formula

The distance formula measures the straight-line space between two points on a coordinate grid, similar to how you might use a ruler to find the distance between two locations on a map. It’s derived from the Pythagorean theorem and calculates this distance by taking the differences in the x-coordinates and y-coordinates of the points, squaring those differences, adding them together, and then taking the square root of that sum. This gives an exact measurement of the shortest path between the two points, regardless of their position on the grid.
