Answer:
(x-3)^2+(y+2)^2=16
Step-by-step explanation:
center (h,k) radius r
(x-h)^2+(y-k)^2=r^2
-- Find any point where y=4
-- Find another point where y=4
-- With your ruler, draw a line between the two points.
You have a horizontal line, and every point on it has y=4 no matter what 'x' is.
The equation for every straight line is [ y = mx+b ].
This is the line where (m = 0) and (b = 4).
