Question

Ordinate of all points on X-axis is
A. 0
B. 1
C. 2
D. 3

Answer 1

Hint: To solve this question, first of all, we need to know about the ordinate. The ordinate in the coordinate system is the term associated with the planar representation of a point. We will use the fact that it refers to the perpendicular distance to reach the answer.

Complete step by step answer:
We have to find the number of ordinates of all points on the X-axis.
We know that in the coordinate system ordinate refers to the perpendicular distance of the point from the X-axis and is parallel to the Y-axis. The ordinate refers to the Y-coordinate of any point. If the ordinate is zero the point lies on the X-axis. The value of ordinate is zero, positive, or negative.
Now, we know that the value of Y-coordinate on X-axis is zero for any point on X-axis. Figure shows the representation of X-axis and Y-axis.

So, the ordinate of all points on the X-axis is zero.
Option A is the correct answer.
Note:
 As ordinate is the other name of the Y-axis in the coordinate system, similarly abscissa is the other name of the X-axis. Abscissa gives the horizontal distance of the point whereas ordinate gives the vertical distance of the point. So, students must have to know the difference between the two. The value of abscissa is zero, positive or negative. Also, don’t be confused between ordinate and coordinate.
