1. An example of an ordered pair would be (4, 6). The x-coordinate would be 4, and the y-coordinate would be 6. The x-coordinate runs horizontally on a graph. A y-coordinate runs vertically on a graph.
2. Three ways to represent a relation are through a formula, domain and range function, or a table.
3. The domain refers to all the values of the independent variable (x-coordinates). The range refers to the numbers you get when you substitute the x values (y-coordinates.)
