It's really a question of what kind of plot you want, since you do not have either x or y as an explicit function of x. Moreover, it's unclear whether you want to regard this as a 2-dimensional curve or as a 3-dimensional surface. In either case, some version of a contour plot will directly give what I think you are asking for: ContourPlot[8x -x^2 + 14y - y^2 == 49, {x, 0, 12}, {y, 0, 12}, Frame->False, Axes->True, AxesLabel->{x,y}] ContourPlot3D[8x - x^2 + 14y - y^2 == 49, {x,0,10}, {y,0,12}, {z,-5,5}, AxesLabel->{x,y,z}] On 5/4/2010 6:30 AM, Trevor Rabey wrote: > I am new to Mathematica and going at snail's pace. > I would like to plot: > > 8x - x^2 + 14y - y^2 = 49 > > Anyone? > > -- > Trevor Rabey > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
