Essential Understandings
Equations and inequalities are models of relationships that exist in real-world situations.
Writing and solving an equation or inequality is an efficient strategy for finding a solution to a real-world problem.
The relationship between two variables can be represented by tables, graphs, and equations.
Situations determine the form that an expression or equation will take.
