You have put up bunch of questions (~5) - without showing single line of work!

My thoughts

I know that this cannot be a straight line because the distance is not 10 between the points. I am thinking it is an ellipse but I have no reference really for why I am thinking that other than the location of the points. But I am not sure why they are giving me a distance, so I think I am suppose to use it but I am not sure how.

The Distance Formula (here) gives a very different value than "10". So what do they mean by "distance"? Are they maybe referring to the length of the graphed (and bendy) segment between them? Have you studied line integrals at all?

Given only this information, about the only thing one can say is that the graph cannot be straight. Can you provide a sample (from your textbook or your class notes) where this sort of question was proposed and answered? Maybe, by looking at that, we can figure out what they're trying to say here.

Thank you! ;)
