Question

The equation of a circle is shown below.

x2 + (y -9)2 = 4

Which statement is true about the center of the circle?
Answer
It is located on the x-axis.
It is located on the y-axis.
It is located in the third quadrant.
It is located in the fourth quadrant

Answer 1

the standard form for a circle is (x-h)^2 + (y-k)^2 = r^2 where (h, k) is the center and r is the radius.

so your equation has center (0, 9) with radius 2. the center is on the y-axis
