Question 7 The point which lies on the perpendicular bisector of the line segment joining A(−3, −4) and B(3, 4) is: (A) (0, 0) (B) (0, 3) (C) (3, 0) (D) (0, 4) Let Line l be the perpendicular bisector of AB And let it intersect AB at point P Since Line l is the perpendicular bisector ∴ Line l ⊥ AB And Line l bisects AB Point P is the mid-point of AB A (−3, –4) B (3, 4) 1 1 l P (x, y) Therefore, Coordinates of Point P = ((𝒙_(𝟏) + 𝒙_(𝟐))/(𝟐),(𝒚_(𝟏) + 𝒚_(𝟐))/(𝟐)) = ((−3 + 3)/(2),(−4 +4)/(2)) = ((0)/(2),(0)/(2)) = (0, 0) So, the correct answer is (A)
