Question

What is the standard form of the equation of the circle in the graph ? Help please, MEDAL

A) (x + 3)2 + (y - 1)2 = 1
B) (x - 3)2 + (y + 1)2 = 2
C) (x + 3)2 + (y - 1)2 = 2
D) (x - 3)2 + (y + 1)2 = 1

Answer 1

std eq of circle
\[x^2 +y^2 = 1\]
if the center is at (0,0)

when center is at (h,k)
\[(x-h)^2 +(y-k)^2 =1\]
(h,k) = (-3,2)
Put h = -3
and k = 1
