Graph input choice

Is it possible to have a graph, an input, and a choice. I would like for students to justify their answer once they type in an equation. I know I can do it by using two different screens (one asks for the equation, and the next one would be the explanation), but would be nice to just do it in one.

Or is there an easier way?

In this situation where would the choice come into play?

There are situations where students are able to take more risks in their answer if they know the teacher will be the only one looking at their answers.

David,

To accomplish what you are looking for, you can select graph and the explain option under choice. See image.
