Question

The point whose ordinate is 3 and which lies on the y-axis is
(a) (3, 0)
(b) (0, 3)
(c) (3, 3)
(d) (1, 3)

Answer 1

The ordinate of a point is the y-coordinate of the point. So, the y-coordinate of the point is 3.

Also, any point on the y-axis has coordinates in the form (0, y).

Thus, the point whose ordinate is 3 and which lies on the y-axis is (0, 3).

Hence, the correct answer is option (b).
