On friday we began looking at graphs. The class had to choose between 4 graphs to see what graph best fits the question that is being asked. Ms.Armstrong also handed out slips so she could add students to the blog. She also handed us an assignment to do for the weekend and is due after the weekend. The assignment is called A Picture's Worth a Thousand Words. We also had to work as groups to help eachother out to pick what graph best answered the question be asked. That is what we basically did on friday. If im missing something leave a comment and i will add it into the blog.

The most obvious way to spot the wrong graph is if there is a loop in the graph because time cannot go backwards.

Hi Dinh,
Thanks for being the first person to scribe for the class. It's never easy to go first, but it's important so that those that follow have an example to follow.
I have a couple of suggestions to improve the quality of your post.
1) More details or examples of how to determine which graph accurately represents a given situation. For example a graph with time as an independant variable cannot have 'loops' because this would mean that time went backwards and that is impossible.
2) The title of your post should indicate the topic that we covered in class so that if you need a refresher in January when studying for exams, it will be easy to find the post you are looking for.
