putting all points in equation of option B satisfies the table . so ans is option B
You have to complete the square. When you do this you get an equation that looks like this: (x-3)^2 + (y+4)^2 = 4. So your center is (3, -4) and your radius is 2. That looks like B to me!!!
The correct answer would be C. $15.
Hope helps
I would say 8.0 Because if you do 12.6-4.9 you get 7.7 ...hope that helped
