Once you have learned how to plot points, you will be able to graph linear equations, or work with ideas like the slope of a line or the distance between two points. Each one gives you a piece of information you can use to plot the point in the coordinate plane. But, depending on the decimal or fraction, you might have to estimate the location of the point a little bit.Ī point is made up of two coordinates: the x-coordinate and the y-coordinate. Even in this case, the same general idea applies. This means that not only can they be positive or negative, but they can also be fractions or decimals. Learn more: Apples and Bananas Education. Everyone will enjoy this active exploration of graphing skills. ![]() Students will receive a set of ordered pairs, then walk to that point on the grid to place their point. The coordinates in an ordered pair can be any real number. Build a giant coordinate plane and get students to walk the grid. What if the coordinates are fractions or decimals? You will move down from the origin instead of up. It is the same idea with a negative y-coordinate. If the x-coordinate is negative, then you will move left instead of right. Then, the x-coordinate will tell you how many units to move left or right, and the y-coordinate will tell you how many units to move up or down. To plot a point, start at the origin, which is the center of the graph (the point (0,0)). ![]() These two numbers tell you in which part of the coordinate plane your point lies. The first number is called the “x-coordinate” and the second number is called the “y-coordinate”. Plotting points is all about reading the numbersĮach number in an ordered pair is called a “coordinate”. In this lesson, we will look at exactly how to do this! The coordinate plane is split into four quadrants. The intersection of these lines creates the origin, which is the point latex(0,0)/latex. The coordinate plane is comprised of a horizontal (x-) axis and a vertical (y-) axis. To plot a point in the xy-coordinate plane (also called the Cartesian coordinate plane), you just have to know how to read the values or numbers in the ordered pair that defines the point. The coordinate plane is a system for graphing and describing points and lines.
