This lesson builds on work that students have done in grade 8 with systems of linear equations. Solving by graphing is taught first in this series on systems to provide a basis for systems of linear inequalities in the next lesson.
?
Draw a system of linear equations with a solution of $${(-1,3)}$$.

$${\left\{\begin{matrix}y=3x+2 \\ 2y=6x-8 \end{matrix}\right.}$$
Change the system so that it has ALL the same solutions.

The following resources include problems and activities aligned to the objective of the lesson that can be used to create your own problem set.
?
Construct a system of two linear equations where $${(-2,3)}$$ is a solution to the first equation but not the second equation and where $${(5,-2)}$$ is a solution to the system.
