Quick Reference Chart - Great for anyone needing a snapshot on solving systems of equations by graphing, substitution and elimination. Steps are listed for each method and detailed examples show how the steps are carried out to find the solution. Special systems are also included. Along with the definition are two examples. One shows how to determine if a system is consistent or inconsistent by comparing the slope and y-intercepts. The other example takes the algebraic approach. Print it in color for maximum detail!
