Question

Find the length of AB

Answer 1

to find AB it will be like this..

everytime you have to find lenght between two points then subtract coordinates of 2nd from 1st..i.e. for AB

AB=OB-OA=(3,3)-(-1,6)=(3-(-1))-(3-6)=(3+1)-(-3)=4+3=7

Answer 2

sorry i don't understand?

Answer 3

\[\sqrt{(x-x)^{2}+(y-y)^{2}}\]

Answer 4

just plug in the x's and y's and you got the length of line AB

Answer 5

@crazycrazy

Answer 6

ok...then a simple way use distance formula..

d=sqrt(x-x1)^2+(y-y1)^2

Answer 7

lol that's what i said
