Can yall me i have to turn this in soon

B

Step-by-step explanation:

The standard form of equation of a circle is

(x-h)^2+(y-k)^2=r^2

Where h is x coordinate of the centre, k is the y coordinate of the centre and r is the radius of the circle

Hence given that h=5, k=-9 and r=12

So the above equation becomes

(x-5)^2+(y-(-9))^2=(12)^2

(x-5)^2+(y+9)^2=144

Hence the answer is B

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept
