centre =(-7,-9)=(h,k)
radius=2
then
the equation of the circle is
(x-h)^2+(y-k)^2=r^2
(x+7)^2+(y+9)^2=2^2
answer is option C.
Answer:
C
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
here (h, k) = (- 7, - 9) and r = 2, hence
(x - (- 7))² + (y - (- 9))² = 2², thus
(x + 7)² + (y + 9)² = 4 → C
