State True or False and write correct statement.

i. In the Cartesian plane the horizontal line is called Y - axis.

ii. In the Cartesian plane, the vertical line is called Y - axis.

iii. The point which lies on both the axes is called origin.

iv. The point (2, -3) lies in the third quadrant.

v. (-5, -8) lies in the fourth quadrant.

vi. The point (-x, -y) lies in the first quadrant where x <0, y < 0.
