Answer:
(- 3, - 4 ) and r = 5
Step-by-step 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
