HELPPPPPP ! Patrick drew the incorrect graph shown below to represent the circle (x – 1)2 + (y + 3)2 = 4
Which statement explains why Patrick’s graph is incorrect?
The radius of the circle should be 2 instead of 4.
The center of the circle should be (1, 9) instead of (1, 3).
The center of the circle should be (1, 3) instead of (1, 3).
The radius of the circle should be 16 instead of 4.

Kindly clarify. Is the circle equation in this form? (x – 1)^2 + (y + 3)^2 = 4

I think the first choice is the answer since the radius of the circle is sqrt4.

***Quote from the link*** (xh)^2+(yk)^2=r^2 This is the standard form of the equation of a circle with radius r and centre (h,k). The equation is (x – 1)2 + (y + 3)2 = 4 Meaning that the radius is sqrt of 4 = 2. In the figure, the radius is about 4. Thus the answer is the first choice.
