What is the y-coordinate of the center of the circle with the following equation:

(x - 5)2 + (y + 18)2 = 36

(5, -18)

Step-by-step explanation:

the original formula for the circle is (x – h)2 + (y – k)2 = r2 the center is (h, k)

so,

(x - 5)2 + (y + 18)2 = 36

h= 5, k=-18

The answer to your question is -18

Step-by-step explanation:

Equation of a circle   (x - 5)² + (y + 18)² = 36

The equation of the circle in standard form is (x - h)² + (y - k)² = r²,

where the coordinates of the center are (h, k).

Then just get the h, k values and change the signs.

h = -(-5) = 5

k = -(18) = -18

the x-coordinate = 5

the y-coordinate = -18
