Posting for Points

This website is designed for student use. Not just for those who were absent in class that day, but to encourage communication, sharing ideas, and discovery. As a way to promote communication, student involvement, and incorporate the ever-desired "Extra Credit", I'm going to try something.
You can earn bonus TEST points for contributing to this website by posting comments. Here is what you need to do:
1. Comment about something you learned in class
2. Post helpful links that you found searching the internet (click the "link" icon in the comments)
3. Post only positive comments!!!
4. To make sure you get your points, enter your name in the following way: First name Last initial, Period #
Example: JonathanF 2
Points awarded will depend upon the value of the comment. A comment of "I'm just posting to get a point" won't get anything, but something like "Today I learned that when you divide an inequality by a negative number, you switch the sign" would get a point. Better yet, something like "Here's a website that has a bunch of help for solving absolute value inequalities" would get 2 points! The big one is if you e-mail me with a picture you found that applies to what we are studying. An example might be a picture in the newspaper of a graph of system of equations.

I will also be putting up a POW: Problem of the Week. You can earn 2 HOMEWORK points for each solution you post. Be sure to give a clear explanation of how you solved the problem. Same sing-in rules apply as above.

Stay Tuned!!

 

Graphing Systems and Inequalities, Part 2

Due to the confusion with Wednesday's assignments (#12 and #13), we spent the first part of the period reviewing 3.1 and 3.3 (Graphing systems of equations and inequalities). The due date for the two assignments has been extended to Monday. At least 1 of those assignments will be collected.
The second part of the block was dedicated to the algebraic methods for solving a system of linear equations (3.2). Substitution and Linear Combinations. There will be a benchmark on each method, as well as systems of inequalities (3.3).
No homework for the weekend (other than finishing #12 and #13).
