Question

7. Find the coordinates of a point A, where AB is the diameter of a circle whose centre is
(2. - 3) and B is (1, 4).​

Answer 1

Answer:

let the coordinates of point is (x, y)

o is the center

o is a midpoint of diameter

=(2-3)=[x+1/2, y+4/2]

=2=x+1/2 , =-3=y+4/2

4=x+1 , =-6=y+4

4-1=x , y=-6-4

x=3 , y= -10

therefore (x, y)=(3, -10)
