I usually have problem in plotting the equations, eg y=2ux/u-x (plotting y wrt x).

Can someone suggest a link where i can get a quick idea of how to do it? Thanks!

'u' is a constant.

what you have is a rational function of the form $\displaystyle y = \frac{ax}{b-x}$ where $\displaystyle \, a,b \,$ are both constants.

vertical asymptote $\displaystyle x = b$ and horizontal asymptote $\displaystyle y = -a$.

here is a link to a series of lessons about graphing rational functions ...
