Systems of Linear Equations (part 2)

Today we had a short quiz on the equations of circles and our new distance formula. We reviewed how to complete the square to find the center and radius of a circle on the cartesian plane. I demonstrated how to complete a question such as number six from lesson three, and then moved on to discuss the homework.

I demonstrated number four (b) from lesson 5, and gave some tips for number 5 from the same lesson. We'll be quizzing a couple of times this week so be sure to ask questions as they come up.
