# The 4 Graph Quadrants: Definition and Examples

The Cartesian plane (or the x-y plane) is a two-line graph on which you plot ordered pairs.

The two intersecting lines of the Cartesian plane make four distinct graph quadrants.

## What Are the 4 Graph Quadrants?

The two lines on the Cartesian plane form four graph quadrants. In this section, we’ll discuss the graph quadrant definition and define each part of the plane.

A quadrant is one of the four sections on a Cartesian plane.

Each quadrant includes a combination of positive and negative values for x and y.

There are four graph quadrants that make up the Cartesian plane. Each graph quadrant has a distinct combination of positive and negative values.

Here are the graph quadrants and their values:

Quadrant I: The first quadrant is in the upper right-hand corner of the plane.

Both x and y have positive values in this quadrant.

Quadrant II: The second quadrant is in the upper left-hand corner of the plane.

X has negative values in this quadrant and y has positive values.

Both x and y have negative values in this quadrant.

X has positive values in this quadrant and y has negative values.

In this diagram, you can see the four graph quadrants, along with whether or not x and y are positive and negative.

Numbers are plotted on graph quadrants in what are known as ordered pairs.

An ordered pair consists of two values, x and y.

In an ordered pair, x is always the first value and y is always the second value. In the ordered pair (5, -2) for instance, 5 is the x value and -2 is the y value.

When plotting an ordered pair, the x value refers to the pair’s horizontal position on the graph. The y value refers to the vertical position.

See how the pair (5, -2) looks when plotted.

Using the following graph quadrant diagram, identify the quadrants for the following ordered pairs.

 Ordered Pair Quadrant (-9, 11) (4, 8) (-3, -4)

 Ordered Pair Quadrant (-9, 11) II (4, 8) I (-3, -4) III

A graph quadrant is one of four sections on a Cartesian plane.

Each of the four sections has a specific combination of negative and positive values for x and y.

You plot an ordered pair on graph quadrants.

Ordered pairs have x and y values

. X is the first value in an ordered pair; y is the second.
