Comment:The applet and activities provide a terrific set of activities. This can be a big help to kids learn y=mx+b linear equations. It is a nice supplement to regular classroom instruction. I think it's worth a few class periods.

Comment:I think this is a great tool to have the students practice writing equations finding slope and y-intercepts. It will also help with computation practice.
