Note that in the previous problem, $$x$$ represented the number of weeks, $$y$$ represented the amount of money, $$400 – 15x$$ represented the amount of money he would have after $$x$$ weeks.  In order to determine whether the shading is correct, a point in the region needs to be selected to determine if it works in the inequality.
