Answer
Please see the graph.
Work Step by Step
$x^2+y^2 \leq 9$
Since the graph has a less than or equal to sign, we use a solid line for the graph.
We pick a point to determine what side of the graph to shade—we pick $(2,2)$.
$x^2+y^2 \leq 9$
$2^2 + 2^2 \leq9$
$4 + 4 \leq9$
$8 \leq 9$ (true)
We shade the side of the graph with the point.
