Graphing Systems of Inequalities - Shade a Single Region (with correctness)

Questions
1

Good afternoon!

I am trying to create a self checking activity where students practice graphing systems of inequalities - that emulate the graphing question type on the new STAAR test. I have found similar activities but not quite what I am looking for.

I need students to graph two lines separately, decide on the line type for each, then click in the region they want to shade. I will appreciate any and all help I can get!

Here’s what I have so far:

I have also attached a picture of what it should look like on STAAR.

That is EXACTLY what I wanted!

How do I know what the region number is? I’m not sure how to read this:

I added in some labels that are only visible when you are editing the graph that show the region number. You can also move the s_haded slider to see which region lights up.

Hello!

What should I delete out if I want to just check a single inequality? Or do I need to just start over?

THANKS!!!

I added in a second screen with a single inequality. It works mostly the same, but I had to change it so that they need to click on the line itself to change the shaded side instead of the region.
