Question

If AB is a diameter and O(2,-3) is the center of a circle. If coordinates of B are (1,4), then

find the coordinates of A.​

Answer 1

$\huge  \star\rm{ \red{Solution:-}}$

Let the coordinates of A be(x,y)

Midpoint of AB

=(x+1/2,y+4/2)

As the coordinates of the midpoint is (2,-3)

So x+1/2=2

=> x=3

And y+4/2=-3

=>y=-10
