Test Friday 10/21

We will have a test Friday 10/21 on linear systems (graphical, algebraic, and matrix solving methods). The relevant textbook sections are 3.1, 3.2, and 4.5; we also had some work outside the textbook (such as 3-variable elimination problems).



Note: I'll be available for extra help after school Wednesday but not on Thursday, so plan ahead if you're expecting to seek help.
