I’ve looked at others Drag and Drop activities but I’m getting stuck on how I’d check that the students did drag the correct number into the correct place.

Am I able to check that a coordinate of a point is in between two values? For instance, if they moved the “2” in between x-values of 1.4 and 1.8 and y-values of 5.4 and 5.7. Since I labeled the point a_3, b_3 can I reference that in the CL of the graph component in an activity?

Here’s the graph that I have worked on so far and I’m just not sure where I should go. I created the Lists because that is what I saw in other activities but I’m not quite sure what to do with that or what to do next.

Thanks in advance for any help anyone can provide.
