Checking a Graph/Sketch

I want my students to sketch a proportional relationship on a graph. I want to be able to see if the sketch is correct with a check in the teacher view, but I do not want to notify students if their sketch is correct or not. I am new to using CL for checking a student sketch of a line. Any help would be appreciated.

Here is a screen that can do that. Let me know if you have questions.

Thank you! I do have a question about this line.

correct = this.number(C)=1

What is C? I do not see it defined anywhere.

Nevermind. I figured it out! Thank you!

This was very helpful thank you so much.

I also have a question about checking a sketch with many possible answers. I would students to sketch a graph whose rate of change is between two values and whose intercept is also between two values. Suggestions for this? Would changing Csub m and Csub b to inequalities work?

I added in a second slide that does that. I just changed it so that it was checking the slope is between two numbers. Those are being populated from the note. But you can just set them directly in the graph and delete the CL override if preferred.
