What is the equation of a circle with center (1, -4) and radius 2?

The answer to your question is letter C

Step-by-step explanation:

Data

Center = (1, -4)

radius = 2

Formula

              (x - h)² + (y - k)² = r²

h = 1

k = -4

r = 2

Substitution, for the substitution, change the original signs of h and k.

             (x - 1)² + (y + 4)² = 2²        

Simplification

             (x - 1)² + (y + 4)² = 4
