ResourceMAP - Properties of Linear Functions - Student Edition

ResourceMAP modules are relatively short and designed for flexible implementation; that is, they can be used in regular classes as well as in special test-preparation settings. Each module contains a set of contextual problems in several formats: multi-part open response, short response, and multiple-choice. Accompanying the problem set are tip sheets that serve several purposes including lists of formulas, calculator instruction, and brief reviews of the module's underlying mathematics. Also provided are teacher notes (the module purpose, the mathematical focus, and implementation commentary), answers to all problems, and (in a few cases) handout masters.

Properties of Linear Functions

One reason linear functions are useful is obvious—they describe things that move in
a straight line or grow at a constant rate. The graphs are easy to recognize since
they are straight. Graphed lines have slopes and intercepts. Sometimes, lines have
special relationships to other lines, like being parallel or perpendicular. In this
activity, you explore these properties of lines in real-world settings.
