Lesson Summary:

In this lesson, you will learn how to recognize a linear relationship in various forms, including tabular data, Cartesian plots, and English descriptions. One way to identify a linear function in a table is to look for a constant difference in outputs when the inputs vary by one. In a Cartesian graph, the constant rate of change can be found by calculating the change in output over the change in input. Finally, you can identify a linear relationship in English descriptions by looking for words like "per" or "fixed cost," which indicate a constant rate of change or initial value, respectively.

Lesson Description:

Recognize a linear relationship in whatever way it may be presented (tabular data, Cartesian plot, English).
