Question

Center at (2, −3); r = √5

Answer 1

(x-2)^2 + (y-k)^2 = √5^2; the graph is in the attached file.

Explanation:

(x−h)^2 + (y−k)^2 = r^2 is the standard form for the equation of a circle, where the center is (h,k) and the radius measures r units.

We can substitute this into a graphing calculator like this;

(x-2)^2 + (y-k)^2 = √5^2

The result is in the file below.

Hope this helps!
