Question

A circle has a center point at the coordinates P ( -3,-3) with a diameter line segment RT where point R has the coordinates at R ( -33,22) . What are the coordinates of point T?

Answer 1

Notice that point T is point R reflected over point P, therefore we use the formula below to find its coordinates:

`(T_x,T_y)=(2(-3)-(-33),2(-3)-22)_{}`

Therefore the coordinates of point T are:

`(27,-28)`
