Question 3
Point ( 0, -7) lies

Thinking process
(i) Firstly, check whether any coordinate of the given point is zero or not.
(a) If x-coordinate is zero and y-coordinate is non-zero, then the point lies on the y-axis.
(b) If y-coordinate is zero and x-coordinate is non-zero, then the point lies on the x-axis.
(c) If x-coordinate and y-coordinate are zero, the point lies on the origin ( or on both the axes.)
(ii) If none of the coordinates is zero, then the point lies in any one of the four quadrants.

A) On the x-axis
B) In the second quadrant
C) On the y-axis
D) In the fourth quadrant

Answer 1

The answer is C.
In point (0, -7), x-coordinate is zero. So it lies on the y-axis and y-coordinate is negative.
So, the point (0, -7) lies on the y-axis in the negative direction.
