Question

Which of the following is true when graphing inequalities in two variables? Just one point is insufficient to verify whether the region is a solution set or not. The line corresponding to the inequality belongs to the solution set only if the inequality is of the or the type. If the inequality is of the < or the type, then the solution set must lie below the x-axis. If the inequality is of the or the (less than or greater than), then two distinct regions exist in the solution set.
