I finally figured it out!!
I've been wanting to create a screen in desmos activities where the students would be given a random equation in slope-intercept form. They would then click and drag the points in a graph to create the corresponding line. Then the activity will give the feedback on whether they are right or wrong.
The first 9 screens, the students are simply given a random equation. On screen 10, the students can practice their little hearts out by clicking on the button to receive a new random equation.

The instructional video will follow once I can organize my thoughts.
Next: Equations that need to be solved for y. :)
