Shade the region where all the half-planes intersect in a darker color.Proceed to the second linear inequality in the system and repeat the three above steps.Now we can shade the half-plane that satisfies the inequality.
For example, ask students to check which of these two ordered pairs (3, 4) or (1, 1) is a solution to the inequality x + 2y or <, we’ll draw a dashed line in the coordinate plane. You can also create a brief bell-work activity where students check if a given ordered pair is a solution to a certain linear inequality. – 2x + y ≤ 2 What Is Solving Systems of Linear Inequalities?įirst, remind students that the solution to a two-variable linear inequality with x and y is an ordered pair (a, b) if the inequality remains true when we replace a and b for x and y. Write a few examples on the whiteboard of systems of linear inequalities: Point out that this set consists of at least two linear inequalities and that we deal with these inequalities all at once. You can write a few examples of linear inequalities in two variables on the whiteboard, such as:Īfter having reviewed linear inequalities, you can explain that a system of linear inequalities is simply a set of linear inequalities containing the same variables. Explain that you’ll work on two-variable linear inequalities. We can also say that the expressions of the forms: ax c, ax + by ≤ c are called linear inequalities. Remind students that a linear inequality is similar to a linear equation however, instead of an equality sign, the linear inequality has an inequality sign (such as, ≤, ≥). You may want to start your lesson by reviewing what linear inequalities are.

Use these strategies in your classroom and see your students’ math knowledge soar! How to Teach Solving Systems of Linear Inequalities What Are Linear Inequalities? To help out, we’ve created a list of strategies to teach this topic. This is why it’s important that math teachers and homeschooling parents have the appropriate teaching strategies in place.
These lessons may not be smooth sailing for all students, especially for students who lack the foundational knowledge of solving linear inequalities and are now asked to jump into solving systems of linear inequalities. Solving systems of equations is a very general and important idea, and one that is fundamental in many areas of mathematics, engineering and science.When algebra 2 students dive into linear systems, they first learn how to solve systems of linear equations and then proceed with solving systems of linear inequalities, including graphing these systems. Going further, more general systems of constraints are possible, such as ones that involve inequalities or have requirements that certain variables be integers. These possess more complicated solution sets involving one, zero, infinite or any number of solutions, but work similarly to linear systems in that their solutions are the points satisfying all equations involved. More general systems involving nonlinear functions are possible as well. Systems of linear equations involving more than two variables work similarly, having either one solution, no solutions or infinite solutions (the latter in the case that all component equations are equivalent). The system is said to be inconsistent otherwise, having no solutions. If all lines converge to a common point, the system is said to be consistent and has a solution at this point of intersection.
In the case of two variables, these systems can be thought of as lines drawn in two-dimensional space. Systems of linear equations are a common and applicable subset of systems of equations. To solve a system is to find all such common solutions or points of intersection. The solutions to systems of equations are the variable mappings such that all component equations are satisfied-in other words, the locations at which all of these equations intersect. What are systems of equations? A system of equations is a set of one or more equations involving a number of variables.
