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 gives us a simple way of finding the distance between two points. From the figure we have PR x2-x1 and QR y2-y1.
Distance between two points 3 42 2 32 3 - 4 2 - 2 - 3 2. The distance formula is Distance x 2 x 1 2 y 2 y 1 2. To find the distance d between the points use the distance formula. Distance between points 4 3 and 3 -2 is 5099.
