What would be four ordered pairs on the graph of the function f(x)= -9/x+2? How to plot ordered pairs in an exact quadrant on a graph paper? If the ordered pair does not lie on the graph â¦ Because infinitely many values of theta have the same angle in standard position, an infinite number of coordinate pairs describe the same point. A function can be represented using ordered pairs. What are the steps in being able to do this? If the ordered pair appears to be on the graph of a line, then it is a possible solution of the linear equation. A quadrant is set up in such a way that the positive numbers are to the right and top, while the negative numbers are to the left and bottom. In the ordered pair (5, -2) for instance, 5 is the x value and -2 is the y value. For example, a student who got two correct answers and 8 incorrect answers will write the ordered pair (+2,-8), and will count two places to the right of zero on the horizontal line, and eight places below zero to place their dots on the graph. A relation is any set of ordered pairs. Ordered Pair Notation, Lean How the x and y values of ordered pair notation relate to a point's location on the x and y planes Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, let's use (2,3) as our ordered pair. Title: Graph Ordered Pairs 1 Graph Ordered Pairs 2 Objective. Find three ordered pairs that solve the equation and draw the graph of each.
