Well, the radius of the circle will be the distance between those two points

anonymous · Answer

d^2 = (4 - (-2))^2 + (9-1)^2 = 6^2 + 8^2 = 100, so d= the radius = 10

anonymous · Answer

so the equation of the circle would be (x+2)^2 + (y-1)^2 = 100

anonymous · Answer

make sense?

anonymous · Answer

yes it does thank you so very much

anonymous · Answer

no problem, any time!
