This unit is all about linear topics, which is a major focus of Common Core Algebra I. We develop general methods for solving linear equations using properties of equality and inverse operations. Thorough review is given to review of equation solving from Common Core 8th Grade Math. Solutions to equations and inequalities are defined in terms of making statements true. This theme is emphasized throughout the unit. Modeling with both linear equations and inequalities is stressed.
