The point whose ordinate is 4 and which lies on y-axis is
a. (4, 0)
b. (0, 4)
c. (1, 4)
d. (4, 2)

Solution:

We know that

Any point which lies on y-axis has (0, y) as the coordinates where y can take any value

Here y = +4 units

Therefore, the point is (0, 4).

✦ Try This: The point whose ordinate is 2 and which lies on y-axis is a. (2, 0), b. (0, 2), c. (1, 3), d. (2, 3)

We know that

Any point which lies on y-axis has (0, y) as the coordinates where y can take any value

Here y = +2 units

Therefore, the point is (0, 2).
