Usually, the coordinates of the centre, and the points you've plotted are sufficient. You might like to add a line from the centre to any point on the circle and indicate that the distance is 7.
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.
