Determine the equation of the circle graphed below.<br> (pt 3 of help fast)

dmitriy555 [2]

<h2>Circular Equations</h2>

Circular equations are typically organized in the following format:

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

(h,k) is the center of the circle
<em>r</em> is the radius

<h2>Solving the Question</h2>

We're given:

The center of the circle: (-4,-7)
The radius: 2 units

Plug these given values into the formula:

$(x-h)^2+(y-k)^2=r^2\\(x-(-4))^2+(y-(-7))^2=2^2\\(x+4)^2+(y+7)^2=2^2\\(x+4)^2+(y+7)^2=4$

<h2>Answer</h2>

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