It's c bro it's 100% C trust me (c)
(x-h)^2 + (y-k)^2 = r^2
r=3
(x-h)^2 + (y-k)^2 = 3^2
the center lies on the y-axis --> h=0
x^2 + (y-k)^2 = 3^2 = 9
expand
x^2 + y^2 -2ky + k^2 = 9
x^2 + y^2 -2ky + (k^2 - 9) = 0
compare to general form
A=1 , B=1 and C =0
D= -2k and E=k^2 - 9
Answer:
B and D
Step-by-step explanation:
slope = 2/7
perpendicular equals negative reciprocal
so slope must be -7/2
A = 2/7
B = -7/2
C = 7/2
D = -7/2
