Check for correct vertical line

Hi there.

I’d like to check for correctness of a vertical asymptote on this slide. What I have here will give me an X if it is wrong, but only a dot if it is correct or not complete.

Can someone please help me with the code?

Check vertical asymptote

You need readOnly: true in the graph’s CL. The dashboard attempts to correct each component that can have a correct sink. You can make a component readOnly so it ignores it when correcting the slide.

Thank you, Daniel. It worked. You are always so helpful.
