Answer:

(x + 4)² + (y - 1)² = 25

Explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

given (h, k ) = (- 4, 1 ) and r = 5 , then

(x - (- 4) )² + (y - 1)² = 5² , that is

(x + 4)² + (y - 1)² = 25
