Question
Find the center-radius form of the circle with the given equation. Determine the coordinates of the center, find the radius, and graph the circle.$$x^{2}+y^{2}-4 x-6 x+9=0$$
Step 1
The standard form of a circle is $(x-h)^2 + (y-k)^2 = r^2$, where $(h,k)$ is the center of the circle and $r$ is the radius. The given equation is $x^{2}+y^{2}-4x-6x+9=0$. Show more…
