I know that the length of AC and AB is sqrt40 and the length of BC is sqrt32. Where do I go from here?

My math teacher didn't go over this very well and I need some help! Math isn't my best subject and I just want to understand! Thank you!

I don't understand how to shift a geometric shape on a coordinate plane and then find the coordinate

As we know quadratic polynomial has parabola (why?) ...and linear has a straight line(why not join a linear with a curved line?)...??....answer me those in BOLD letters.
