Answer:

(- 3, - 4 ) and r = 5

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

(x + 3)² + (y + 4)² = 25 ← is in standard form

(x - (- 3))² + (y - (- 4))² = 5²

with centre = (- 3, - 4) and r = 5
