Question

what is distance formula ...?

Answer 1

$d = \sqrt({x2} - {x1})² ({y2} - {y1})²$

where

( x1 , y1 ) r the coordinates of the 1st point &

( x2 , y2 ) r the coordinates of the 2nd point .

Answer 2

Distance formula for points

(x1, y1) and (x2, y2) :

$\boxed{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$
