If y coordinate of a point is zero, then this point always lies
a. in I quadrant
b. in II quadrant
c. on x - axis
d. on y - axis

Solution:

It is given that

y-coordinate is zero

Abscissa can be any number x and the ordinate is zero

In the point (x, 0) x can take positive or negative value

(x, 0) lies in the x-axis

Therefore, the point lies on the x-axis.

✦ Try This: Point (2, 0) lies a. on the x-axis, b. in the second quadrant, c. on the y-axis, d. in the fourth quadrant

If the coordinate of a point is zero, then this point always lies a. in I quadrant b. in II quadrant c. on x - axis d. on y - axis

Summary:

The coordinate axes divide the plane into four parts called quadrants. If the y coordinate of a point is zero, then this point always lies on the x - axis
