Yes, but you have to tell it what to plot. In general, we plot *functions*, not curves. You could do an implicit plot, though; see sage: implicit_plot? for more details. Or you could algebraically solve for y=mx+b and then plot that. Also, if you just use sage: plot(XXX) you will want to put in endpoints for x; otherwise you just get the default inputs, from -1 to 1.
