Question

If the perpendicular distance of a point P from the x-axis is 5 units and the foot of the perpendicular lies on the negative direction of x-axis, then the point Phas (a) x-co-ordinate = -5. (b) y-co-ordinate = 5 only. (c) y-co-ordinate = -5 only. (d) y-co-ordinate = 5 or -5​

Answer 1

Answer:

We know that, the perpendicular distance of a point from the X-axis gives y-coordinate of that point. Here, foot of perpendicular lies on the negative direction of X-axis, so perpendicular distance can be measure in II quadrant or III quadrant. Hence, the point P has y-coordinate = 5 or -5.
