    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.

    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
