The formula is a2 b2 c2. Distance x 2 x 1 2 y 2 y 1 2. Mathematically if you want to determine the distance between two points on a coordinate plane you use the distance formula.
Given the two points x1 y1 and x2 y2 the distance d between these points is given by the formula.
For each example I will substitute the given values into the equation and then solve. Dx 1-x 2 2 y 1-y 2 2. Distance x 2 x 1 2 y 2 y 1 2. Given the two points x1 y1 and x2 y2 the distance d between these points is given by the formula.
