1. Algebra 2 graphing help

Hey guys, what's up? I know this is going to sound dumb, but I forgot how to do it.

xy=-3. How would you graph that? Im drawing a blank right now. Thanks for the help!

recall that the form $y=\frac{1}{x}$ is called an equilateral hyperbola

first rewrite the equation as $y=-\frac{3}{x}$ the - sign will flip the graph and the 3 will expand it.

here is graph of $y=\frac{1}{x}$ and $y = -\frac{3}{x}$

3. Thanks so much!
