How do I create a Desmos system of two variable linear inequalities item?
In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a system of two variable linear inequality question. A system of two variable linear inequality question requires students to plot a system of linear inequalities 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 validate answers.
You can create any item type through the Item Editor. You can also use the Item Editor to add passages, add item-level tools, and save the item. To open and use the Item Editor, learn more about:
- Creating an item in your personal item bank
- Creating an item in district item bank as an administrator
- Creating an item from within an assessment
Note: 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.
