Question

distance between coordinates (1,-3) and (-2,0)​

Answer 1

LetA=(1, - 3) here, x1=1,Y1=-3

LetB=(-2,0) here,X2=-2,Y2 =0

Distance formula:-

AB^2 =(X2-x1)^2 + (Y2-Y1) ^2

AB^2 =(-2-1)^2 +(0-(-3))^2

AB^2 =(-3)^2 +(+3)^2

AB^2 =9+9=18

AB^2 =18

Apply root both side

rootAB^2 =root18

AB=3root2
