To find the center and radius of the given circle equation , we can rewrite it in standard form. Completing the square for the and terms, we get . Thus, the center is and the radius is .
Now, when graphing the circle, start by plotting the center . From this point, draw a circle that extends units in all directions. For the intercepts, set to find the x-intercepts and set for the y-intercepts. Solving these will provide points where the circle crosses the axes.
