Solution
Ordinate of all points on the x-axis is 0.
Explanation:
Ordinate of all points on the x-axis is zero. Because ordinate (or y-coordinate) of a point is perpendicular distance of this point from the x-axis measured along the y-axis.
If point lies on x-axis, then the perpendicular distance of point from x-axis will be zero, so ordinate will be zero.
