in the IV quadrant.
(iii) The x-coordinate of the point (2, 0) is positive and
the y-coordinate is zero. So, it lies on the x-axis.
(iv) The x-coordinate and the y-coordinate of the point
(2, 2) are positive. So, it lies in the I quadrant.
(v) The x-coordinate and the y-coordinate of the point
(-3, -6) are negative. So, it lies in the III quadrant.
Question: 8
Which of the following points lie on 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), I (3, 3).
Solution:
A point lies on the y-axis, if its x-coordinate is zero.
Here, x coordinates of the points C(0, 1), D(0, 0), E(0,
-1) and G(0, 5) are zero. So, these points lie on the y-
axis.
Also, D(0, 0) is the intersection point of both the axes.
So it lies on the y- axis as well as on the x- axis.
