What, if anything, have you tried? Even if you know you have the wrong answer, show us your work. This is "Free Math Help, " not "We do your homework for you." If you show us your work, we can give you a hint to help you figure it out. If you're completely stuck, here's a hint for part a. Your goal there is to form an equation of a circle, that looks like (x−h)2 + (y−k)2 = r2

Hi, I manage to find the radius which is sqrt 2 and the coordinates (-2,3)
(x+2)2 + (y−3)2 = 2
that is all i did so far any more hits on part 2 etc will help me get this done quicker ty
Okay, so part b gives an equation of a line: y = -x + c. This line must be tangent to the circle C, from part one. Since a tangent line intersects a circle exactly once, what does that say about the line? Think about where the point of intersection between the line and the circle must be to guarantee only one intersection.
