Question

Question 8
Which of the following points lies on the y-axis?
A (1, 1), B(1, 0), C(0, 1), D(0, 0), E(0, -1), F(-1, 0), G(0, 5), H(-7, 0) and I(3, 3)

Answer 1

We know that a point lies on the Y-axis if its x-coordinate is zero.
Here, x-coordinate of points C(0,1), D(0, 0), E(0, -1) and G(0, 5) are zero.
So, these points lie on Y-axis.
Also, D(0, 0) is the intersection point of both the axes, so we can consider that it lies on the y-axis as well as on x-axis.
