This product is a good overview of Linear Relationships and how to recognize them in symbolic form (equations), tabular form (tables), graphical form (graphs), and contextual/verbal form (words/stories). It can be used as an overview for units on Linear Relationships. I've used it as a review for upper-level math students, such as Algebra 2 and Calculus students. If you like this handout, you may also appreciate "Recognizing Multiple Representations of Quadratic Relationships."
