Question

Directions: Write an equation for the circle shown on the graph in standard form. 15. ​

Answer 1

Answer: x(squared) + (y + 2)(squared) = 36

Explanation:

The center of the circle is at (0 , -2), so we will eliminate the x value by just writing x(squared), and then we will write the y value as (y + 2)(squared) because the standard form for a circle is

(x - h)(squared) + (y + 2)(squared) = r(squared)

And if we count from the center to the top point of the circle, the number would be 6, so we would square 6 which would be 36.
