B) In II quadrant
C) On x-axis
D) On y-axis

Solution

The answer is C.
If y-coordinate of a point is zero, then this point always lies on the x-axis.
Because the perpendicular distance of the point from x-axis measured along the y-axis is zero.

Question 10 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

The answer is C. If y-coordinate of a point is zero, then this point always lies on the x-axis. Because the perpendicular distance of the point from x-axis measured along the y-axis is zero.
