You do not have to do so. However, many people find graphical representations easier to understand.

To find the solutions.
How are solutions linear inequalites determined graphically?
Graph both inequalities and the area shaded by both is the set of answers.
Do solutions to systems of linear inequalities satisfy both inequalities?
Yes.

To find the solutions.
When graphing inequalities why do you shade the graph?
The part that is shaded represents all the possible solutions. An inequality has solutions that are either left or righ, above or below or between two parts of a graph.
How are solutions linear inequalites determined graphically?
Graph both inequalities and the area shaded by both is the set of answers.
Graph the system of inequalities y-2 and x3?
Graph the following Inequalities: x > 3
What is the definition of equivalent inequalities?
The definition of equivalent inequalities: inequalities that have the same set of solutions
Why it is necessary to use an empty circle to graph solutions of inequalities?
It is not necessary - it is a convention to distinguish between the end points of a range being included or not in the solution.
Do solutions to systems of linear inequalities satisfy both inequalities?
Yes.
How do you solve questions that say which graph best represents the system of inequalities?
The solution to a system of inequalities is where the solutions to each of the individual inequalities intersect. When given a set of graphs look for the one which most closely represents the intersection, this one will contain the most of the solution to the the system but the least extra.
How do you know which region of the graph of a system of linear inequalities contains the solutions?
If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.
Must solutions to systems of linear inequalities satisfy both inequalities?
Yes.
Which of the inequalities is represented by the graph?
