What is the general form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)?

anonymous · Answer

x2 + y2 − 4x + 2y + 1 = 0

x2 + y2 + 4x − 2y + 1 = 0 

x2 + y2 + 4x − 2y + 9 = 0

x2 − y2 + 2x + y + 1 = 0

anonymous · Answer

just complete there squares...and then see what it comes to be...

huh?

anonymous · Answer

The equation x2 + y2 − 2x + 2y − 1 = 0 is the general form of the equation of a circle. What is the standard form of the equation?

anonymous · Answer

(x − 1)2 − (y − 1)2 = 1

(x − 1)2 + (y + 1)2 = 3

(x + 1)2 + (y − 1)2 = 1

(x − 1)2 + (y + 1)2 = 1

anonymous · Answer

its standard form..

(x-a)2 + (y-b)2 = r2
