For a given system of linear inequalities, the solution set will be one of the four regions determined by the intersection of two lines. Explain how the solution set is found.
You graph the linear inequlities.
Find all the regions they form (whether bounded or unbounded). Then select a point inside the region and see if it satisfies all the inequalities, if yes then you found the solution set. If not go to a different region. Do this until you find the proper region.
