3-41.

Rewrite $x^2-2x+y^2-29=0$ in graphing form, sketch the graph, and label the important points.

Complete the square. To begin, move the constant term to the right side of the equation.

$x^2-2x\ +\ ?\ +\ y^2=29\ +\ ?$

The graphing form of the equation of a circle is $(x−h)^2+(y−k)^2=r^2$. $(h,k)$ is the center of the circle and $r$ is the radius.
