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.
