The 4 Graph Quadrants There are four graph quadrants that make up the Cartesian plane. Here are the graph quadrants and their values: Quadrant I: The first quadrant is in the upper right-hand corner of the plane. Graph Quadrants Diagram In this diagram, you can see the four graph quadrants, along with whether or not x and y are positive and negative. Graph Quadrant Numbers, Explained Numbers are plotted on graph quadrants in what are known as ordered pairs.
See how the pair 5, -2 looks when plotted. Graph Quadrants Example Problems Using the following graph quadrant diagram, identify the quadrants for the following ordered pairs. Ordered Pair Quadrant -9, 11 4, 8 -3, -4 Graph Quadrants Example Problems: Answers Find the answers for the above graph quadrants example problems below.

Each point can be identified by an ordered pair of numbers; that is, a number on the x -axis called an x -coordinate , and a number on the y -axis called a y -coordinate. Ordered pairs are written in parentheses x -coordinate, y -coordinate. The origin is located at 0,0. Note that coordinates are often written with no space after the comma.
The location of 3,2 is shown on the coordinate plane below. The x -coordinate is 3. The y -coordinate is 2. To locate 3,2 , move 3 units to the right on the x -axis and 2 units up on the y -axis. The coordinate axes divide the plane into four regions called quadrants or sometimes grid quadrants or Cartesian coordinate quadrants.
Students often ask, how are quadrants numbered? A common heuristic is to think of the numbering happening in the same order that we write the letter C. In Grade 5, students do not usually need to know the numbering system, but should recognize that the appropriate quadrants for ordered pairs can be identified according to the signs of the numbers. There are many opportunities for discourse that focus on all quadrants of the coordinate plane.
Have students brainstorm how someone making an animation or video game might use it, for example. Or show students a variety of graphs taken from different activities and books and have them share what they notice and wonder. A coordinate plane lets you both visualize and calculate the length of a line segment.
Although students do not learn to calculate the length of slanted line segments until learning the Pythagorean Theorem typically in Grade 8 , a four-quadrant plane is enough to find the length of horizontal or vertical line segments.
For horizontal line segments, the length is the difference between the x -coordinates of the endpoints. For vertical line segments, the length is the difference between the y -coordinates of the endpoints.
Around Grade 5, functions are graphed from tables of given values. The numbers in the quadrant are the ordered pair a, b where 'a' is the x- coordinate and 'b' is the y-coordinate. To understand how to plot a point in the four quadrants, we need to observe the signs of an x-coordinate also called abscissa and a y-coordinate also called ordinate.
This gives an idea about the quadrant in which the given point lies. For example, we are given a point P -4,6. Let's plot the point D 5,-3 on a cartesian plane.
First, observe the sign to identify its quadrant. The x and the y axes divide the plane into four graph quadrants. In words, we call them first, second, third, and fourth quadrant.
All the quadrants are different from each other based on the position and symbol of the x and y-coordinates. Quadrant I contains the positive values of x and y, so it is considered a positive quadrant. Other than this, quadrant II has negative x-coordinates and positive y-coordinates, quadrant III has both negative coordinates and quadrant IV contains the positive values of x but negative values of y. The right upper quadrant is the first quadrant containing all the positive values of the x and y axes starting from 0, i.
