Today in class we covered section 7.5, which covered special types of systems of linear equations. Up until today we have covered systems that had one solution (meaning that the two graphs intersected at a specific point). In today's lesson we learned that systems can also have no solution (linear graphs are parallel) or infinitely many solutions (linear graphs are the same line).
Homework due Friday 1/20: Pg. 429 #6, 8, 10, 20, 22, 25, 31-33
