Graphing Linear Functions

• You can represent the relationship between two quantities, such as an input and output, by using a table, a rule or equation, or a graph.
• In order to graph a linear equation create a table. Choose input values of your choice. In most situations, choose small values including zero. If the function includes a fraction you may want to choose multiples of the denominator so that you can simplify the fractions to whole numbers, which are easier to graph. The input value is the x-coordinate and the output value is the y-coordinate.
• Any ordered pair that makes an equation true is a solution.
