Determine the equation of the circle graphed below.

Step-by-step explanation:

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

2

+(y−k)

2

=r

2

here

r = 7. (the circle is symmetrical with y - axis )

h = 0. and k = 1

Thus equation of circle is,

(x - 0) {}^{2} + (y - ( - 1)) {}^{2} = {7}^{2}(x−0)

2

+(y−(−1))

2

=7

2

x^2 + (y+1)^2 = 49

the answer is b i just did that
