{(-1, 3), (-2, 5), (-3, 3), (-5, -3)}. To show that the four ordered pairs belong together in a set, we list them with commas in between each and brackets around the group. As with other methods of representing relations, we can check the characteristics of a set of ordered pairs to determine if it is a function.he next table does not represent a function. The x column has two values that are 3, and they correspond to two different values for y. Remember, when a single input can produce multiple outputs, the relation is not a function.
In an ordered pair the x-. values and y-values can be positive, negative, or zero. Examples of orderd. pairs are: (-3, 4), (5,-8), (0,6), (-7,-7) and, (9,5). This is called an ordered pair because the order of the numbers is important. If you put the numbers in. the wrong spots the point or ordered pair is not always the same as you can see in the example below. The x-coordinate tells how far away from the y-axis a point is and the sign of the coordinate tells which.
