Lines

Here is a summary and review of what we've been learning over the last few days. There is a neat little java applet you can play with to see how changes in the slope and y-intercept effect the graph of a line.

Try the exercises here too if you wish. Towards the bottom of the page you'll find 3 animations of how changing slopes effect the graphs of lines with different y-intercepts. (Click on the animated gif links.)

How many lines do you see?


Update!
Since I noticed some of you are struggling with the homework I thought this online lab might help. The text in some places may be long, but stick it out and try it -- you'll learn a lot. And that's what we're all about, isn't it? ;-)

Good thing my sister has studied pre-cal, I get lots of help from her! Yeah, and I agree that the supply lists should have an older smart sibling as a requirement!
