On graph paper, graph $x^2 + y^2 = 9$. 12-43 HW eTool (Desmos). Homework Help ✎

Use the eTool below to help you with this problem.

1. Consider the inequality $x^2 + y^2 \le 9$. Does the point $(0, 0)$ make this inequality true? What is the graph of $x^2 + y^2 \le 9$? Explain.

Where does the shading go according to the inequality?

2. Now consider the inequality $x^2+y^2 > 9$. Does the point $(0, 0)$ make this inequality true? What region is shaded? Describe the graph of this inequality.

How is this inequality different from the first? How is the graph different?
