Explain the steps necessary to find the center and radius of the circle below. x2 + 4x + y2 ‒ 6y = 9 then, find the center and the radius of this circle and sketch the graph of the circle.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
