Determine the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1) by following the steps below.

Use the distance formula to determine the radius: d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot
Substitute the known values into the standard form: (x – h)² + (y – k)² = r².

What is the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1)?
x2 + (y + 4)² = StartRoot 5 EndRoot
(x – 1)² + (y + 2)² = 5
(x + 4)² + y² = 5
(x + 2)² + (y – 1)² =
