Question

one end of a diameter of a circle is at (2,3) and the center is (-2,5), find the coordinates of the other end of the diameter.

Answer 1

Answer:

[ ( -2 + x )/ 2 , (-3 +y )/ 2. ]= (2, -5)

Comparing both sides

(-2 + x)/ 2 = 2 ; (-3 + y)/ 2 = - 5

(-2 + x) = 4 ; (-3 + y) = - 10

x = 6 ; y = -7

The co ordinates of other end = ( 6, -7 )
