Question

Write the y-coordinate of a point which lies on x-axis
​

Answer 1

Answer:

The y-coordinate of a point lying on X-axis is 0.

So, point lying on the x-axis are of the form (a,0).

Among the given points only (3,0) has y-coordinate 0.

Hence the answer is (3,0).

Answer 2

Answer:

If a point lies on the x-axis then its y-coordinate is 0. ... The origin has coordinates (0,0).
