उत्तर
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 y-axis as well as on x-axis.
