I am looking to teach a introduction lesson on linear inequalities for an Algebra 1 course. I would like for my students to explore the idea of how you decide where to shade by whether or not a point works in that section of the graph. I want them to pick their own point, whether it be by putting it into a table or math input or using a draggable point on a given graph. Then on the next screen, to plot all these coordinates on a graph with the given line to show which part of the graph should be shaded. Is there a way to even do this?

Also, I have been trying to read through other related posts, but I am new to using the more advanced parts of Desmos and programming in general.
