This comprehensive notes packet is a perfect supplementary or instructional material for Algebra 1 and 2 students; it can serve as a general notes packet, a study guide, or a supplementary material for students who need extra review of 1) slope, 2) functions, 3) graphing equations. 4) domain and range, 5) systems of equations, 6) systems of inequalities, 7) systems word problems, and 8) profit functions. The twenty-page guide breaks down each of the eight topics by giving verbal instructions for solving each type of problem, one completely-solved sample problem for each topic and sub-topic, and one practice problem for each topic and sub-topic. An answer key is featured at the end of the packet for each of the twelve practice problems, in addition to a short vocabulary section (particularly helpful for students for whom English is not their first language). Color-coding is used meaningfully to highlight important pieces of the problems.
