Plotting 2D function of two variables

favorite

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.

I don't understand what you are trying to plot. If x is 1 and y is 1, tehn g[1,1)=-1. What exactly do you want to 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]

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"]
