The solution region which is the intersection of the half-planes is shown in a darker shade. Usually only the solution region is shaded which makes it easier to see which region is the solution region. Graph the system of inequalities beginmatrix x 3: : : : : : : : y leq -x 2 endmatrix. Learning Objectives, define solutions to systems of linear inequalities. Graph a system of linear inequalities and define the solutions region. Verify whether a point is a solution to a system of inequalities.

A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Example, graph the system of inequalities beginmatrix ygeq 2x-3: : : : : : : : ygeq -3: : : : : : : : : : : : : : : yleq -0.8x2.5 endmatrix. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.

Consider a point that is not on the line - say, ( 0, 0 ) - and substitute in the inequality. 0 2 3 ( 0 ) 4. Shade upper half of the line. Similarly, draw a dashed line of related equation of the second inequality y 2 x 1 4 which has a strict inequality. Draw a dashed vertical line x 4 which is the related equation of the third inequality. Here point ( 0, 0 ) satisfies the inequality, so shade the half that contains the point. The solution of the system of inequalities is the intersection region of the solutions of the three inequalities. Create a free account to continue.

The point ( 0, 0 ) does not satisfy the inequality, so shade the half that does not contain the point ( 0, 0 ). The solution of the system of inequalities is the intersection region of the solutions of the two inequalities. Example 2: Solve the system of inequalities by graphing: 2 x 3 y 12 8 x 4 y 1. Rewrite the first two inequalities with y alone on one side. 3 y 2 x 12 y 2 3 x 4 4 y 8 x 1 y 2 x. Now, graph the inequality y 2 3. The related equation is y 2 3.

If they do, shade the half-plane containing that point. If they don't, shade the other half-plane. Graph each of the inequalities in the system in a similar way. The solution of the system of inequalities is the intersection region of all the solutions in the system. Example 1: Solve the system of inequalities by graphing: y x 2 y 3. First, graph the inequality y. The related equation is y.

Since the inequality is, not a strict essay one, the border line is solid. Graph the straight line. Consider a point that is not on the line - say, ( 0, 0 ) - and state substitute in the inequality y., this is false. So, the solution does not contain the point ( 0, 0 ). Shade the lower half of the line. Similarly, draw a dashed line for the related equation of the second inequality y 3 x 5 which has a strict inequality.

Consider the shaded triangle in Figure. We can use the method described above to find each linear inequality associated with the boundary lines for this region. In this case, our system is: Tutorial Details, approximate time 20 Minutes, pre-requisite concepts, students should be able to write the equation of a line from its graph and vice versa (graph a line from its equation and define and graph a system of linear.

Graphing Systems of Two linear Inequalities. Graphing Systems Involving Absolute value inequalities. Writing and Solving Problems Involving Systems of Linear Inequalities 0/0 0 Conquered. To graph a linear inequality in two variables (say, x and y first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line. If the inequality is strict ( or graph a dashed line. If the inequality is not strict ( or graph a solid line. Finally, pick one point that is not on either line ( ( 0, 0 ) is usually the easiest) and decide whether these coordinates satisfy the inequality or not.

### Linear, equations as Models

Choose a test point not on the boundary line. Use the test point to determine which half-plane should be shaded. The use of the test point can be bypassed and last three steps can be summarized with the following for non-vertical business boundary lines: If the inequality is of the form. If the inequality is of the form then the region below the line about is shaded and the boundary line is solid. If the inequality is of the form y mx b, then the region above the line is shaded and the boundary line is dashed. If the inequality is of the form then the region above the line is shaded and the boundary line is solid. Recall that a system of linear inequalities is a set of linear inequalities in the same variables.

be represented graphically with a dashed or dotted boundary line. Finally, our graph should include the points (x, y) which satisfy the inequality. We can determine these points by taking a point on one side of the line and testing its coordinates in our inequality. If the inequality is then a true statement, we shade the half-plane including that point; otherwise, we shade the half-plane that does not include the point. In this example, we can use the origin (0, 0) as a test point. Notice that it is not true that and so we shade the half-plane that does not include the origin. In order to graph a linear inequality, we can follow the following steps: Graph the boundary line. Determine if the boundary line should be dotted or solid (that is, check whether the inequality is strict or inclusive, respectively).

Now you know, after completing this tutorial, you will be able to complete the following: Write a system of linear inequalities in two variables that corresponds to a given graph. Everything you'll have covered, recall that a linear inequality is an inequality involving linear functions. A linear inequality on the plane can have one of the following forms: Notice that all of these linear inequalities have linear equations, which can be associated with them if we replace the inequality with an equality. So all of the inequalities in the first row are associated with the linear equation y mx b, those in the second row with y b, and those in the third row with. Graphically, we can represent a linear inequality by a half-plane, which involves a boundary line. The boundary line is precisely the linear equation associated with the inequality, from drawn as either a dotted or a solid line. In addition, the half-plane involves a shaded portion of the plane either above or below the boundary line (or to the left or right of a vertical boundary line). For example, in Figure 1, the linear inequality is represented on the coordinate plane.
