I believe the ansr would be (-6,-4) I say this becuase if it's positive on the y axis the X axis will be negative and if it's being reflected the coordinates will be backwards. If this answer is wrong I'm truly sorry, but I hope this helps!
46 i think. sorry if i’m wrong
Yes because square root of 4 is 2 and square root of 16 is 4. 4+2=6
