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.
Collect the y terms on one side $\displaystyle xy-y = 5-2x$ and factorise $\displaystyle y(1-x) = 5-2x$ and divide to give $\displaystyle y = \frac{5-2x}{1-x}$
Bear in mind there will be a vertical asymptote at $\displaystyle x=1$
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
