How do I create a Desmos number line inequality item?

In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a Desmos number line inequality item. A Desmos number line inequality question requires students to plot a line segment by controlling the end points and selecting conjunction or disjunction. 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.
