Counting unique equations in table

I saw this task someone made and wanted to make a slight change to Slide 8 (if it’s even possible).

  1. Can it count the number of unique linear functions students type into the table?
  2. Can it aggregate this number for the whole class so it says something like “The lowest number of unique linear functions in the class is ____”

Depends what you mean by “unique”. Is x+y=10 different from y=-x+10?

You can certainly check if there’s a set of lines each with distinct properties, but that’s not quite the same thing as unique representations.That said, it would be a lot of code to do that. And yes it would be possible to aggregate that, but again, just a very large amount of checking.
