Question

find the coordinates of a point a where ab is the diameter of a circle whose Centre is bracket 2, - 3 and the point B is bracket 1, 4​

Answer 1

let A will be (x,y) and O(2,-3) is the centre of circle.

then O is mid point of A and B

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

x+1=2×2 y+4 =-6

x=4-1 y=-10

x=3

coordinate of A be (3,-10)
