Hey Carlos Oliveira,

Step 1: You should start with this link ( http://www.opentk.com/doc/chapter/0 )[1]

Step 2: For a simple x=y graph , copy-paste the code snippet provided in the link[1] and remove the game.RenderFrame part and replace with code snippet pasted just below

game.RenderFrame += (sender, e) =>

            {
                GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit);

                GL.Begin(PrimitiveType.Lines);
                GL.Color3(Color.White);
                //YAxis
                GL.Vertex2(0.0f, 2.0f);
                GL.Vertex2(0.0f, -2.0f);

                //X-Axis
                GL.Vertex2(2.0f, 0.0f);
                GL.Vertex2(-2.0f, 0.0f);
                GL.End();

                GL.Begin(PrimitiveType.Points);
        // Plotting the Graph
                GL.Color3(Color.DeepSkyBlue);
                for(float i=0;i<2.0;i=(float) (i+0.001))
                {
                    GL.Vertex2(i,i);
                }
                GL.End();
                game.SwapBuffers();
            };

Thanks, Hope it helps

Also like Christos mentioned a simple search would have landed you on the initial chapters of openTK
