# Thread: How do you graph xy + 2x - y = 5 ?

1. ## How do you graph xy + 2x - y = 5 ?

How do you graph xy + 2x - y = 5 ? I'm currently using Lybniz in Ubuntu 10.10

Or could you suggest any other software ?

Thank you.

2. Collect the y terms on one side $xy-y = 5-2x$ and factorise $y(1-x) = 5-2x$ and divide to give $y = \frac{5-2x}{1-x}$

Bear in mind there will be a vertical asymptote at $x=1$

As for graphing it I use kmplot but since it will pull in a lot of KDE/Qt dependencies. Of course plotting the graph should be simple in lybniz

Edit: yay for another linux user
