You can put this solution on YOUR website!
you can always start by graphing an inequality
graph%28+500%2C+500%2C+-5%2C+5%2C+-5%2C+5%2C+4%28x-3%29%5E2%2B9%28y%2B1%29%5E2%3C36+%29
The center is always determined by what is added to x and y: it is (3, -1).
This is not a circle so I am not sure how to answer the question about radius.
