Grade 8 Module 4: Linear Equations
In Module 4, students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, lines, and linear equations in this module. Students learn to apply the skills they acquired in Grades 6 and 7, with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables.

Linear expressions in x are a special type of expression. Linear expressions are expressions that are sums of constants and products of a constant and x raised to a power of 0, which simplifies to a value of 1.
Non-linear expressions are also sums of constants and products of a constant and a power of x. However, non-linear expressions will have a power of x that is not equal to 0 or 1.
