Q12 of 23 Page 322

The point s P and Q lie on 1st and 3rd quadrant respectively. The distances of the two points from x – axis and y – axis are 6 units and 4 units respectively. Let us write the co-ordinates of mid-point of line segment PQ.

The coordinates of point P will be –(6, 4), because it lies in 1st quadrant. And point Q will be (– 6, – 4), because it’s in 3rd quadrant.

Let the co-ordinates of mid-point of PR be (x, y).


And, since it is a mid-point –




⇒ x = 0 and y = 0


⇒ The mid-point is actually the origin(0, 0).
