The point (2,2) does not lie on the graph because it does not satisfy the equation. The graph passes through the point (0,0) and has a slope of 1, so the equation of the line is y = x. When x = 2, y should also equal 2, but instead y = 3. Therefore, (2,2) does not satisfy the equation and does not lie on the graph.
