Ordered Pairs Worksheets
When it comes to the coordinate graphing system, we use ordered pairs to describe locations within the graph itself. An ordered pair is composed of a location that is described with a two-dimensional location in the format (x, y). The x coordinate tells us where the point is located in a horizontal (left-right) direction and the y coordinate tells us where the point is located in a vertical (up-down) direction. Ordered pairs can help us visual understand things like position on a map, but they are critical to assisting us in understanding the nature of algebraic expressions and equation which can be used to model systems of just about any kind. These worksheets and lessons will help make students very comfortable working with ordered pairs on a Cartesian plane.

Understanding the Coordinate System
We use the coordinate plane to plot points and visually display lines. It has many different applications to the real world. It can be used to model structures and the movement in an environment. The coordinate system allows us to understand the nature of algebraic relationships. When lines are plotted in an image, it makes it easier to spot interacts than just using raw data points. We can spot trends and comprehend the trends of a system. When we plot lines and find two that intersect, we know that the equations have positions where they are the same. You can use the x and y intercepts to understand more about equations. They are listed in the order x and then y (x, y). The x values move from left to right. Just like the number line, if the value is negative it will move to the left of the 0 and if it positive, it will move to the right. The origin of the graph is where the two axes meet and it forms the foundation of the entire system. This is where all numbering begins, and it is denoted as the (0,0) position. Take a look at all these parts of a coordinate graph below:
When Plotting Ordered Pairs: What does the positive and negative value of the x and y coordinate indicate?
A cartesian coordinate system can have both positive and negative values lying on the x and y-axis. The cartesian coordinate system helps in describing the algebraic relationship in a visual manner and helps create and interpret concepts of algebra.
The purpose behind the negative and positive axis and plotting dots on those planes are to indicate the location of the graph and its position with respect to the origin (0,0). These values can be used to explain a specific position in physical space like a map or an algebra expression which gives an idea where something is located. As we know the x-axis moves in a horizontal left to right manner. A negative x value is to the left of the origin and a positive value is to the right of the origin. The y-axis is similar, positive values move above the origin and negative values are locate below the origin.
Because the two axes break the system into four unique areas it often helpful to be able to different portions of the plane. We call each of those portions quadrants. The upper right quadrant is numbered 1. In a counterclockwise fashion we number the remaining quadrants 2-4. Quadrant 1 (Positive x-axis, Positive y-axis), Quadrant 2 (Negative x-axis, Positive y-axis), Quadrant 3 (Negative x-axis, Negative y-axis), Quadrant 4 (Positive x-axis, Negative y-axis). To indicate that a dot is located on the left side of the origin, it can mean that it lies either on the second or the third quadrant. We can use the concept of quadrants to explain and model position changes on a coordinate system. This is helpful to spot trends and make accurate forecasts.
