If y-coordinate of a point is zero, then...

If y-coordinate of a point is zero, then this point always lies

A

in I quadrant

B

in II quadrant

C

on X-axis

D

on Y-axis

Text Solution

Verified by Experts

The correct Answer is:
C
If y-coordinate of a point is zero, then this point always lies on X-axis . Because perpendicular distance of the point from X-axis measured along Y-axis is zero.
