anonymous · Answer

x^2 + y^2 = 25 if rotating left across origin....unless this is a circle

break it down into y= x +/- ___ to see the graph

anonymous · Answer

its a circle, ould you explain a little more

anonymous · Answer

ok so the formula of a circle is (x - h)^2 + (y - k)^2 = radius^2...where h & k are the origin of the circle.. 

Since x and y are alone, the origin of the circle is the actual origin (0,0)....meaning rotating the circle 45 degrees about (0,0) doesn't change anything

anonymous · Answer

at least not geometrically
