Ordinate of all points on the x-axis is
(A) 0
(B) 1
(C) -1
(D) any number
Answer: [A]
Solution.
We know that the coordinate of every point on x-axis is (x, 0)
i.e., (7, 0), (1, 0) etc.
So the y-coordinate on the x-axis is always zero.
Hence the ordinate of every point on x-axis is 0.
Therefore option (A) is correct
