The basic bresenham algorithm consider drawing a line on a raster grid where we restrict the allowable slopes of the line to the range if we further restrict the linedrawing routine so that it always increments x as it plots, it becomes clear that, having plotted a point at x,y, the routine has a severely limited range of options as to where it may put the next point on the line.
