Question

AB diameter of circle with the centre at origin. what are the coordinates of B if coordinates of A are (3,-4)?

Answer 1

look... if AB is diameter and o is origin that it is sure that o will be midpoint of ab... let b be (h, k)
therefore (0,0)=(h+3/2,k-4/2)
h= - 3,k=4

Answer 2

Hi,

X=-3

Y=4
