Good Has only completed more then 24 equations and shows work on all equations.	Excellent Has completed 30 equations, shows work on all equations.
Graphing	Poor Graph is not labelled at all.	Fair Either graph does not properly show a pair of parallel lines or a pair of perpindicular lines	Good Graph not clearly labelled	Excellent Has a graph that demonstrates a pair of parallel lines, and a pair of perpindicular lines.
