Write the equation of the circle with center (0, 0) and (−1, −3) a point on the circle. a) x2 + y2 = 4 b) x2 + y2 = 5 c) x2 + y2 = 10 d) x2 + y2 = 16

ANSWER

C)

EXPLANATION

The center of the circle is (0,0).

The circle passes through (-1,-3).

The radius can be obtained using the distance formula:

The equation is given as:

Where (h,k) is the center and r is the radius.

This implies that;

this doesn't make sense lol

the answer is d. 75%
