We got back the chapter 12 test today and went over any questions in class together. We then got started on chapter 13 and the topic of coordinate geometry. We went through the basic ideas of graphing and how to determine the distance between two points using both the pythagorean theorem and the distance formula. We also introduced the idea of how to work with circles on the coordinate grid and how to come up with an equation for circles at the origin.
Assignment: section 13-1; page 525-526; CE 1-10, 12
