Correct coding so teacher summary has boolean check

I am trying to code so that student can correct what type of slope and type in the number. I have tried three different and similar codes, but every time when I try the check is still not coming up in the teacher summary. I want a quick check of right or wrong on the summary so I don’t have to scroll through. How do I code correctly?

Each slide has a sketch with a graph background, multiple choice, and numeric input.

For the choice component you need only this code
correct: choice.matchesKey
That should fix it.
