## How do I create a Desmos two variable linear inequality item?

In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a two variable linear inequality question. A two variable linear inequality question requires students to plot a linear inequality on a graph in response to a stimulus. After you select the question type, you can use the math editor to add details for the question, view a student preview, and verify auto-grading is working correctly. Once the question is published to an item bank, you can add the question to an assessment.

Notes:

• If you do not see the Desmos Items (Paid Upgrade) section in the Question Type drop-down menu, your institution does not have a paid Desmos upgrade.
• District and school administrators (admins) can also create items directly in the district item bank.
