LINEAR FUNCTIONS

This unit is a study of linear functions which are the most basic algebraic functions.  When working with a set of ordered pairs in a linear function, the y-values will be dependent on the corresponding x-values.  There are various ways to graph linear equations such as making a table of x and y values or plotting two points connected by the slope of the line. Slope will be examined closely by comparing the steepness of lines and also by calculating the slope using the slope formula.  The graphs of linear equations will be predicted based on keeping some values constant while changing others. The unit concludes with examining rates of change and direct variation.
