We are to find the center-radius form of the equation of each circle and graph it.

center is (5,-4) radius is 7

so I come up with

(x-5)^2 + (y+4)^2 = 49

I plot on paper the center point of (5,-4) and from there go 7 in in NSEW on my graph paper, then connect the dots for a circle.

What now - Should I now come up with center radius co-ordinates?

How and from what?

I don't see the connection with all I have done to this point.
