D. x^2+y^2=5

Answer 1

A

Answer 2

lol degenerate circle

Answer 3

A Degenerate Circle has a radius of 0

Answer 4

never heard of it!!!

Answer 5

nwm ,you are right

Answer 6

No, you can't have a negative radius.

The form his (x-a)^2 + (y-b)^2 = r^2
since it is r^2, there are no negative radii

Answer 8

Answer 9

Exactly, just a dot at the center point.

Answer 10
