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

Question

dakid88 · Answer

Distance between (-2,1) and (-4,1) is 2.   (x - (-2))^2  + (y - 1)^2 = (2)^2  --> 

(x+2)^2 + (y-1)^2 = 4  -->  x^2 + 4x + 4   +  y^2 - 2y + 1  = 4  -->

x^2 + 4x + y^2 - 2y + 5  =  4  -->  x^2 + 4x + y^2 - 2y + 1 = 0
