Question
Write the center-radius form of the circle with the given equation. Give the center and radius, and graph the circle. $$x^{2}+y^{2}-4 x-6 y+9=0$$
Step 1
We also leave some space to complete the square for both x and y terms. The equation becomes: $$ (x^{2}-4x) + (y^{2}-6y) = -9 $$ Show more…
