3. Independent Practice Check Textbook p. 447-450
4. Independent Practice Check Textbook p. 454-457
5. Vocabulary Exactly One Solution = Consistent and Independent
Graphing Intersecting Lines
Substitution Produces a Solution
Elimination Produces a Solution
Infinite Solutions = Consistent and Dependent
Graphing Same Line
Substitution Variables all disappear Left with True Sentence
