An ordered pair x y represents co-ordinate of the point where x-coordinate or abscissa is the distance of the point from the centre and y-coordinate or ordinate is the distance of the point from the centre. The distance formula always serves as a useful distance finding tool when it comes to finding the distance between two specific points. Take the coordinates of two points you want to find the distance between.
Distance Formula and Pythagorean Theorem.
Know the distance formula. D x 2 x 1 2 y 2 y 1 2. It uses the following formula give points are x1y1 and x2 y2 SQRT x2-x1 x2-x1 y2-y1 y2-y1. The length of the hypotenuse is the distance between the two points.
