Question

Determine the equation of the circle graphed below.

Answer 1

`(x + 7)^2 + (y + 4)^2 = 4`

Explanation:

The equation of a circle with radius r and center (h, k) is:

`(x - h)^2 + (y - k)^2 = r^2`

This circle has center (-7, -4) and radius 2.

The equation is:

`(x + 7)^2 + (y + 4)^2 = 4`
