Question

How do you graph `(x - 3)^ 2 + (y + 1) ^2 = 9`?

Answer 1

Draw a circle with `(3, -1)` as center and `3` as radius.

Explanation:

Standard equation of a circle with `(a, b)` as center and `r` as radius is

`(x-a)^2+(y-b)^2=r^2`.

Hence, in the above, `(3, -1)` is the center and `3` is the radius.

Hence to draw the graph, just draw a circle with `(3, -1)` as center and `3` as radius.
