To find the solutions.
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.
You do not have to do so. However, many people find graphical representations easier to understand.
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.
to solve a linear in equality you have to write it out on a graph if the line or shape is made ou of strate lines its linear
Graph both inequalities and the area shaded by both is the set of answers.
Graph the following Inequalities: x > 3
The definition of equivalent inequalities: inequalities that have the same set of solutions
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
