The coordinates of the point are positive. And join those ordered pairs to get a shape.Similarly, you can plot several ordered pairs.Highlight that point and write the ordered pair there.Then take the mentioned number of units on the x-axis and y-axis.Check out the signs of those real numbers to determine under which quadrant the given point lies.Let us take any ordered pair having 2 real numbers as abscissa and ordinate.Have a look at them and follow them whenever necessary. In the following sections, we are giving the simple steps and instructions to mark ordered pairs on a coordinate graph effortlessly. The format of an ordered pair is (x_coordinate_value, y_coordinate_value). The first value in the ordered pair is called the abscissa or x coordinate and the second value is called the y coordinate or ordinate. It has two real numbers enclosed by braces ‘(‘, ‘)’ and separated by a comma. The ordered pair is a point in the coordinate plane having both x-coordinate and y-coordinate values. Steps to Plot Ordered Pairs on a Coordinate Graph So, the x coordinate value is positive and the y coordinate value is negative. The last quadrant or fourth quadrant is available right-hand side to the third quadrant and below the first quadrant.The plane enclosed by x’oy’ is called quadrant 3. The third quadrant is available below the second quadrant and here both abscissa, ordinates are negative.The plane enclosed by yox’ is quadrant 2. The second quadrant is available to the left side of the first quadrant, it has abscissa as negative and ordinate as positive.The plane having xoy is called quadrant 1. The first quadrant, is a quadrant having both x and y coordinates positive.Some important points about the quadrants are mentioned here: Every coordinate graph has 4 quadrants namely quadrant 1, quadrant 2, quadrant 3, and quadrant 4. This image shows how exactly the coordinate graph looks like. Each graph paper has both coordinate axes (x-axis, y-axis) is known as the cartesian plane. The line having the name X’OX is called the x-axis, the other line having the name Y’OY is called the y-axis, and the point O is called the origin. On a coordinate graph two perpendicular straight lines having names X’OX, Y’OY are called the coordinate axes. What is meant by Coordinates Axes, Quadrants? This coordinate graph is also called the coordinate plane or cartesian plane or cartesian coordinate system. The point o intersection of axes is called the origin. The horizontal line is known as the x-axis, and the vertical line is known as the y-axis. Coordinate Graph DefinitionĪ coordinate graph has two lines that are perpendicular to each other. So, students are advised to go through this entire article to get clarity on what is meant by the coordinate graph, why it is used, solved examples, and how to represent an ordered pair in the coordinate graph. It is needed for the students who are studying the class 8 coordinate geometry concept. You can represent ordered points in the coordinate graph. It is also called the cartesian plane or coordinate plane. Most graphing calculators require similar techniques to graph an equation.A coordinate graph is a two-dimensional plane having two perpendicular lines intersect at the midpoint called the origin. Graphing Equations with a Graphing Utility Keep in mind, however, that the more points we plot, the more accurately we can sketch the graph. There is no rule dictating how many points to plot, although we need at least two to graph a line. Otherwise, it is logical to choose values that can be calculated easily, and it is always a good idea to choose values that are both negative and positive. Of course, some situations may require particular values of \(x\) to be plotted in order to see a particular result. Note that the \(x\)-values chosen are arbitrary, regardless of the type of equation we are graphing.
