    Distance between points (x1,y1) and (x2,y2) is \(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\) does this help ??

    @goformit100 then there is one concept - Distance formula. If (x1,y1) and (x2,y2) are two given points on any co-ordinate plane, the distance b/w 2 points is given by - \[\sqrt{(x1-x2)^2 + (y1-y2)^2}\]
