Linear Functions are functions that have a constant rate of change. The graph of a linear function is a line, whose slope can be found algebraically and graphically as the constant rate of change.

This chapter shows a few different ways to graph linear functions, such as using a table of values, using the $x\text{-}$ and $y\text{-}$intercepts, and using the slope and $y\text{-}$intercept.

We also explore the effects of transformations on linear functions in both the rules and graphs of functions. Linear inequalities are introduced and graphed, demonstrating their solution sets as half-plane regions of coordinate planes.
