I have:



g(x, y) = x * (y + 3) - 5


I want a 2D plot of the "points" where x and y are 1, 2, 3 .. 10 .
How to do this? I could only find 3d plotting.

A simple 2D plot



g[x_, y_] := x*(y + 3) - 5
tp = Table[
 Plot[g[x, y], x, 1, 10, PlotRange -> -5, 120, 
 PlotLabel -> "y", y, AxesLabel -> "x", "g[x,y]"], y, 1, 10];

gifs = ListAnimate[tp]


enter image description here



Alternatively you could plot g vs y and then vary x.

      g[x_, y_] := x*(y + 3) - 5


      You could use either ContourPlot



      ContourPlot[
       g[x, y], x, 1, 10, y, 1, 10, Contours -> Range[0, 120, 5],
       ContourLabels -> All,
       PlotLegends -> Automatic,
       ColorFunction -> "Rainbow"]


      enter image description here



      or DensityPlot



      DensityPlot[
       g[x, y], x, 1, 10, y, 1, 10,
       PlotLegends -> Automatic,
       ColorFunction -> "Rainbow"]

                            You could use either ContourPlot



                            ContourPlot[
                             g[x, y], x, 1, 10, y, 1, 10, Contours -> Range[0, 120, 5],
                             ContourLabels -> All,
                             PlotLegends -> Automatic,
                             ColorFunction -> "Rainbow"]


                            enter image description here



                            or DensityPlot



                            DensityPlot[
                             g[x, y], x, 1, 10, y, 1, 10,
                             PlotLegends -> Automatic,
                             ColorFunction -> "Rainbow"]
