    Graphing Hyperbola

    Hello, I am having a problem with graphing an hyperbola in the equation of 4y^2/9 - 81x^2=1

    I don't know how to set it up to be in the equation of y^2/a^2 - x^2/b^2=1

    \frac{4y^{2}}{9} - 81x^{2} =  1

    \frac{y^{2}}{\frac{9}{4}} - \frac{x^{2}}{\frac{1}{81}}

    this is in the form of \frac{y^2}{a^2} - \frac{x^2}{b^2} = 1

    where a = \frac{3}{2}  , b =\frac{1}{9}

    Can you graph now??
