This may not be much, but I wanted to share. I have this set up so that a random slope intercept equation will show.
It has a 1/5 chance of having a fraction slope and integer b-val
1/5 chance of having a integer slope and fraction b-val a
1/5 chance of having fraction slope and fraction b-val
and a 2/5 chance of all being integers.
When students write the standard form, it only accepts it when the x coefficient is positive and written in Ax+By+C form.
Again, may not be much but spent the last two hours trying to work out the kinks so I figured I’d share in case anyone needs something like it.
