Which equation represents a circle with the same radius as the circle shown but with a center at (-1, 1)?
A. (x – 1)^2 + (y + 1)^2 = 16
B. (x – 1)^2 + (y + 1)^2 = 4
C. (x + 1)^2 + (y –1)^2 = 4
D. (x + 1)^2 + (y – 1)^2 = 16
Answer (2)
The equation representing a circle centered at (-1, 1) is C: ( x + 1 ) 2 + ( y − 1 ) 2 = 4 . This option has the correct center, and its radius is defined as 2. It's essential to confirm circles are accurately centered while also considering their radii.
