Answer:

The answer to your question is the third option

Explanation:

Data

Center = (2, -16)

A (2, -13)

P (-1, -16)

Equation

(x - h)² + (y - k)² = r² or

(x₁ - h)² + (y₁ - k)² = (x₂ - h)² + (y₂ - k)²

Substitution

(2 - 2)² + (-13 + 16)² = (-1 - 2)² + (-16 + 16)²

The signs in my equation and the one in the options are different but the results are the same
