To determine the graph that represents the solution set of a system of inequalities, you need to plot each inequality on a coordinate plane. The solution set will be the region where the shaded areas of all inequalities overlap. Typically, the boundaries of the inequalities will be represented by solid lines (for ≤ or ≥) or dashed lines (for < or >). Identifying the correct graph involves checking which regions satisfy all the inequalities simultaneously.
To verify the solutions of a system of linear inequalities from a graph, check if the points satisfy all the inequalities in the system. You can do this by substituting the coordinates of each point into the original inequalities to see if they hold true. Additionally, ensure that the points lie within the shaded region of the graph, which represents the solution set. If both conditions are met, the solutions are confirmed to be true.
Not every system of inequalities has a solution. A system of inequalities can be inconsistent, meaning that there are no values that satisfy all inequalities simultaneously. For example, the inequalities (x < 1) and (x > 2) cannot be satisfied at the same time, resulting in no solution. However, many systems do have solutions, which can be represented as a feasible region on a graph.
To determine the solution region for a system of inequalities, first graph each inequality on the same coordinate plane. For linear inequalities, use a dashed line for "less than" or "greater than" and a solid line for "less than or equal to" or "greater than or equal to." Shade the region that satisfies each inequality; the solution region is where all shaded areas overlap. This overlapping area represents all the points that satisfy all inequalities in the system.
It represents the point of intersection on a graph.
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.
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.

Linear inequalities in two variables involve expressions that use inequality symbols (such as <, >, ≤, or ≥), while linear equations in two variables use an equality sign (=). The solution to a linear equation represents a specific line on a graph, while the solution to a linear inequality represents a region of the graph, typically shaded to show all the points satisfying the inequality. Moreover, linear inequalities allow for a range of values, whereas linear equations specify exact values for the variables.
To determine the solution of a system from its graph, look for the point where the graphs of the equations intersect. This intersection point represents the values of the variables that satisfy all equations in the system simultaneously. If the graphs do not intersect, the system may have no solution, indicating that the equations are inconsistent. If the graphs overlap entirely, it suggests that there are infinitely many solutions.
The Feasible Region
When graphing inequalities you use a circle to indicate a value on a graph. If the value is included in the solution to the inequality you would fill in the circle. If the value that the circle represents is not included in the solution you would leave the circle unshaded.
