An equation states that two expressions are equal, while an inequality relates two different values.

Recall that a function is a relation that assigns to every element in the domain exactly one element in the range. Linear functions are a specific type of function that can be used to model many real-world applications, such as production costs or depreciation. In this chapter, we will explore linear functions, their graphs, and how to relate them to data.
- 2.1: The Rectangular Coordinate Systems and Graphs
- In this section, we will learn how to use grid lines to describe locations and changes in locations.
- 2.2: Linear Equations in One Variable
- In this section, we will investigate problems that involve equations with a single variable.
- 2.3: Models and Applications
- In this section, we will set up and use linear equations to solve real-world applications.
- 2.4: Complex Numbers
- In this section, we will explore a set of numbers that fills voids in the set of real numbers and find out how to work within it.
- 2.5: Quadratic Equations
- In this section, we will learn how to solve problems that involve quadratic equations.
- 2.6: Other Types of Equations
- In this section, we look at equations involving rational exponents, polynomial equations, radical equations, absolute value equations, and other types of equations.
- 2.7: Linear Inequalities and Absolute Value Inequalities
- In this section, we will explore various ways to express different sets of numbers, inequalities, and absolute value inequalities.
