Answer:
(x + 2)² + (y + 7)² = 9
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 the radius
Here (h, k) = (- 2, - 7) and r = 3, thus
(x - (- 2))² + (y - (- 7))² = 3², that is
(x + 2)² + (y + 7)² = 9
Answer:
(x+2)^2 + (y+7)^2 = 9
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
Substituting into this equation
(x--2)^2 + (y--7)^2 = 3^2
(x+2)^2 + (y+7)^2 = 3^2
(x+2)^2 + (y+7)^2 = 9
