Another thing to remember is when you are putting positive and negative lines on a graph the positives alway need to go west and the negatives go east. If by chance you need any saved Euklid files they are on the coursework drive but you have to open Euklid and do the following: File+Load.
We tried playing a game that related somehow to what we were doing but it wouldn't load so that didn't happen.
For today there is no homework but feel free to try out 3,4 or 5.
Here are some screenshots from Euklid.
