(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am working on these problems, systems of equations and inequalities. Now, I know how to do the problem and find the solution set, but our teacher said that we can check our answer by graphing it with out graphing calcs.

I have a Ti89 Titanium. How do I input/graph the following with my ti89:

x^2 + y^2 = 4

x^2 + 2x + y^2 = 0

Any help would be great! Thanks guys

2. Relevant equations

3. The attempt at a solution
