In the xy-plane, the line y = k is the perpendicular bisector of the line segment PQ and the line x = b is the perpendicular bisector of the line segment RQ. If the coordinates of the point R are (-b, -k), then what are the coordinates of the point P?	Choices.
A) (-5b, -5k)
B) (-3b, -3k)
C) (2b, 2k)
D) (3b, 3k)
E) (5b, 5k)
firstly the Question tells us that RQ and PQ are perpendicular at Q..   Now the coordinates of the point R are (-b, -k), so R is at a distance of 2b from line x and at dist of 2k from line Y..   as line X bisect RQ .... length of RQ =4b and coord (3b,-k)..   as line Y bisect PQ .... length of PQ =4k and coord (3b,3k).ans (3b, 3k)
