Checking Correctness for Movable Point

I copied the slide I found below and am trying to modify it. I want it to show correctness when students move the point to a specific location, such as (3,2). I want to be able to modify this on various slides. Thanks for any help.

Here you are. You can change x_0 and y_0 in the graph or in the CL (the CL will override the graph, so delete the graph CL if you want to change the correct values in the graph):

Oh, and I added a 0.25 step to the a and b sliders, so they’re a little easier to snap to the graph.

This is exactly what I needed! Thank you!
