Answers

Answered by harishguptadesigns

Step-by-step explanation:

Correct option is

Ordinate=5 or −5

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.

Hence option D is correct.
