Best ResponseYou've already chosen the best response.0Distance between points (x1,y1) and (x2,y2) is \(\huge d=\sqrt{(x_1x_2)^2+(y_1y_2)^2}\) does this help ??

Best ResponseYou've already chosen the best response.2@goformit100 then there is one concept  Distance formula. If (x1,y1) and (x2,y2) are two given points on any coordinate plane, the distance b/w 2 points is given by  \[\sqrt{(x1x2)^2 + (y1y2)^2}\]
