I've been asked to plot a graph of x≠0. ≠ aparently means not equal to, but i dont know how i am supposed to do this, surley that would be everyvalue but 0?
The points in the graph of "$\displaystyle x\ne 0$", in the xy-plane, are all points in the plane except those for which x= 0. That is, all except the vertical line x= 0.
(Just realized- that's exactly what "mathgirlie" said!)
