Question

What is the general form of the equation for the given circle?
x^2 + y^2 − 8x − 8y + 23 = 0

x^2 + y^2 − 8x − 8y + 32 = 0

x^2 + y^2 − 4x − 4y + 23 = 0

x^2 + y^2 + 4x + 4y + 9 = 0

Please can someone help me with my question

Answer 3

Someone please help me :/

Answer 4

I think it is

Answer 5

B but I am not 100% that is my best guess

Answer 6

@Bphillips99, based on the two coordinates given, can you tell me:

1) The radius of the circle.
2) The coordinates of the centre of the circle.

This is all we need to find the equation of the circle.

@riley33, B is not correct.
