Remind students that the slope-intercept form is as follows: y = mx + b.

Point out that we’ll arrange each equation into the slope-intercept form. Write an example of a system of equations on the whiteboard, for instance: If the lines are parallel, there is no solution, as there isn’t any intersection. The solution of systems of linear equations is correct if it satisfies the given equations. Highlight that the point of intersection, which is an ordered pair, represents the solution to the system of linear equations. Then we need to find the intersection of these two lines. Point out that to do this, we need to plot the graph of each equation in the same coordinate system, which will result in two straight lines. The solution to this equation is an ordered pair (x, y) that worked in the equation.įor example, one solution to the equation y = 2x – 3 is the ordered pair (1, – 1) because by substituting the values for the variables in the equations, we see that they work and the equation is true.Įxplain that when solving systems of equations by graphing, we need to find an ordered pair that is basically a solution to both of the linear equations in the given system of equations. So how do we perform this graphing of equations?Īsk students to think of linear equations again, for example, y = 2x – 3. We call this graphing systems of equations. The easiest way is solving systems of equations by graphing. This includes solving systems of equations by substitution, solving systems of equations by addition, etc. Provide an example of systems of linear equations:Įxplain that there are several ways in which we can solve systems of equations. A system of linear equations is simply when we have a set of two (or more) linear equations that we need to work on together. In this lesson, explain that you will be teaching about systems of linear equations. You may also want to check out this article on teaching linear equations if students need further guidance in linear equations. The degree of x and y in a linear equation is always 1. Linear equations are equations that, when plotted on a graph, result in a straight line. You can start your lesson by asking them to provide a few examples of linear equations, or simply write a few linear equations on the whiteboard, such as:

Luckily, there are various ways in which you can help students master this topic with great ease! Without further ado, here are some great guidelines that you can follow to help you best prepare for success in your classroom! How to Teach Graphing Systems of Equations What Is a System of Equations?īy now, students are familiar with what a linear equation is and what it looks like. In algebra 2, this is one of the most important introductory lessons when it comes to learning about linear systems.īut if you’re a math teacher, you probably encountered at least one student that doesn’t find graphing systems of equations as the most fun lesson out there! Graphing systems of equations refers to solving systems of equations by graphing and tables.
