Answer

Refer to the graph below.

Work Step by Step

RECALL: The graph of the equation $x^2+y^2=r^2$ is a circle whose center is at the origin and whose radius is $r$ units. The given equation can be written as $x62+y^2=6^2$. Thus, its graph is a circle with center at the origin and whose radius is $6$ units. To graph this equation, perform the following steps: (1) Plot the center $(0, 0)$. (2) Plot the following points: 6 units above the center: $(0, 6)$ 6 units below the center: $(0, -6)$ 6 units to the right of the center: $(6, 0)$ 6 units to the left of the center: $(-6, 0)$ (3) Connect the four points listed in Step (2) above using a smooth curve to form a circle. Refer to the graph in the answer part above.
