To find the distance between A11 and B34 we form a right angled triangle with AB as the hypotenuse. D x 1 -x 2 2 y 1 -y 2 2 How the Distance Formula Works. 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 between x1 y1 and x2 y2 is given by.
Using the distance formula shown in the above article find the horizontal distance between the two points by subtracting -8 from 2 which is 10. We use the 2D formula when working in the x-y plane and the 3D distance formula when working in the x-y-z system. D x 1 -x 2 2 y 1 -y 2 2 How the Distance Formula Works.
