Question

Which equation describes the circle
with center (5,-1) and radius 7?

Answer 1

Answer:

B

Step-by-step explanation:

circle equation is :

$(x - a) ^{2} + (y - b) ^{2} = r^{2}$

With (a) being the x coordinate of the centre and (b) being the y coordinate of the centre, r is the radius;

make sure to square the radius when using it in this formula
