Studdy Solution
Write the equation of the circle using the center I(1,1) I(1, -1) and radius 2 2 :
The equation of a circle is given by:
(xh)2+(yk)2=r2 (x - h)^2 + (y - k)^2 = r^2
Substitute h=1 h = 1 , k=1 k = -1 , and r=2 r = 2 :
(x1)2+(y+1)2=22 (x - 1)^2 + (y + 1)^2 = 2^2
(x1)2+(y+1)2=4 (x - 1)^2 + (y + 1)^2 = 4
The equation of the circle is:
(x1)2+(y+1)2=4 \boxed{(x - 1)^2 + (y + 1)^2 = 4}
