2. Under the standard (r.g)Hcoordinate system, a grid of points with integer coordinates is given in the picture below. Here, the bottom-left point is the origin (0,0) and the top- right point has coordinate (6,3). The coordinates of the remaining points can easily be computed accordingly. A walk on a grid of points with integer coordinates that uses the steps (1,0) (east-step) and (0, 1) (north-step) is called a north-eastern lattice patih
