**Today: ** We were super fast and talked about many things after spending some time going over your homework. We talked about the two equations given to you on p. 72: y=kx is the equation for a direct variation, and k=y/x is the equation for the constant of variation. All of the problems in this section relate to these two facts. We also went over the idea of linear models: basically, you are using an equation to show what line matches the data or information given. The examples we did in class, while giving the definitions on the outline, are all linear models.

**Homework: **At lest finish the first part before class tomorrow. p. 74/ 2, 6, 7, 11, 12, 15-25 odd, 33, 35; p. 81/ 1, 2, 4, 7, 15-18, 22, 23, 27.

**Next Class: **We will go over the first part of the homework, but please check these before you come to class! The faster we go over questions, the faster we can get to the fun new stuff! We will be talking about the absolute value function/ graph and related functions and graphs. I will also give you the review sheet to help you with the review for the **test on Wednesday**.
