Question 6
Ordinate of all points on the x-axis is

A) 0
B) 1
C) -1
D)​​​​​​​ Any number

Answer 1

The answer is A.
The ordinate of all points on the x-axis is zero because ordinate ( or y-coordinate) of a point is the perpendicular distance of this point from the x-axis measured along the y-axis. If the point lies on the x-axis, then the perpendicular distance of point from x-axis will be zero.
So, ordinate will be zero.
