You can choose the equation of the line or curve via the input box, it will accept lines of the form [math]y=mx + c[/math] and [math]ax+by=c[/math], but curves must be given as [math]y=\ldots[/math].[br][br]There are 10 blue points next to the plot graph button, drag these points to positions which lie on the graph, they will turn red if correctly positioned. Only use the plot graph button if you are really stuck.
