Franklin the fly starts at the point $(0,0)$ in the coordinate plane. At each point, Franklin takes a step to the right, left, up, or down. After $2$ steps, how many different points could Franklin end up at?

After n steps.....he can reach ( n + 1)^2   lattice points  (points with integer coordinates)  =  (2 + 1)^2  =   9
