Coordinates and Quadrants

In the Cartesian coordinate system, every point can be represented by an ordered pair of coordinates (x, y). The coordinates are used to locate a point on a plane. The plane is divided into four quadrants: I, II, III, and IV.

Understanding Quadrants

The quadrants are numbered in a counterclockwise direction:

Quadrant I

x is positive (+)
y is positive (+)

Quadrant II

x is negative (-)
y is positive (+)

Quadrant III

x is negative (-)
y is negative (-)

Quadrant IV

x is positive (+)
y is negative (-)

Determining the Quadrant of a Point

To determine the quadrant of a point, we need to look at the signs of the x and y coordinates.

If x is positive and y is positive, the point lies in Quadrant I.
If x is negative and y is positive, the point lies in Quadrant II.
If x is negative and y is negative, the point lies in Quadrant III.
If x is positive and y is negative, the point lies in Quadrant IV.

The Point (-3, 0)

Let's determine the quadrant of the point (-3, 0).

x is negative (-3)
y is zero (0)

Since x is negative and y is zero, the point (-3, 0) lies on the x-axis. The x-axis is the horizontal axis that divides the plane into the upper and lower halves. All points on the x-axis have a y-coordinate of zero.

Conclusion

In conclusion, the point (-3, 0) lies on the x-axis, but not in any of the four quadrants. It is an important concept to understand when working with coordinates and graphs.
