None of these is on the circle.

Answer 1

Plug in the points and see which one makes the equation false.

Answer 2

idk how :(

Answer 3

For (6,0), let x=6, and y=0. See if it is true.

(6-3)^2+(0+4)^2=25?

25=25 yes, (6,0) lines on the circle

Answer 4

Look for the point which does not give you 25
