Q. the point (4,-3) is on one end of the diameter of a circle centre (6,5). Find the coordinates on the point on the opposite end of that diameter.
Center is the mid point of the opposite points of a diameter. If (x, y) are the co-ordinates of the other end of the diameter, then
find the mid point of the diameter and equate it to the co-ordinates of the center.

Q. the point (4,-3) is on one end of the diameter of a circle centre (6,5). Find the coordinates on the point on the opposite end of that diameter.

$$\displaystyle \frac{5-(-3)}{6-2}=\frac{8}{2}$$

$$\displaystyle 6+2= 8$$
$$\displaystyle 5 + 8 = 13$$
