The distance between two points is calculated using the distanceÂ formula d = √ (x2 - x1)2 + (y2 - y1)2, where (x1,y1) and (x2,y2) are the coordinates of the two points and "d" indicates the distance. The distance formul... More »

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, t... More »

In math, the term "distance between two points" refers to the length of a straight line drawn between the two points on an x-y axis. The distance can be determined by finding the change in the y axis and the the x axis a... More »
