16 pages. This mini-unit (3 days) introduces the y=mx+b form as a general formula for linear functions. From this form, students learn to write equations for linear functions given:
* Slope and y-intercept
* Slope and a point on the line
* Two points on a line
It is designed for introductory algebra students who already have familiarity with:the definition of a function (but not necessarily function notation), coordinate graphing, identifying slope of a linear function from a gr
