4-4 Geogebra

August 2, 2010

I created a screencast to illustrate the applet I created in Geogebra for helping students see the affects that changing the slope and y-intercept have on a line. The screencast can be found here, and if you want to play with the applet yourself, it can be found here.

I tried to upload the applet to the applet collection page and it gave me some trouble at first. I messed around with the class wiki a little bit ( I hope that is ok) and I put a link to the Applet Collection page in the navigation bar on the left side of the screen. I was then able to upload the applet.



  1. Thanks for the Collection page! Great idea, Peter!

    I followed instructions for embedding into wiki from this page and embedded your applet there. I just had to make it 1000 by 1000 or sliders weren’t visible.
