The coordinates of one end point of a diameter of a circle are `(4,-1)` and the coordinates of the centre of the circle are `(1,-3)` . Find the coordinates of the other end of the diameter.

Explanation

Let AB be a diameter of the circle having its centre at C(1, -3) such that the coordinates of one end A are (4, -1).


Let the coordinates of B be (x,y).



Since C is the mid-point of AB.


Therefore,the coordinates of C are `((x+4)/2,(y-1)/2)`
