This course is a part of Algebra I, a 21-course Topic series from Khan Academy.

Solve various word problems that involve real world relationships that can be represented by linear equations or functions.

This course contains 4 segments:

Interpreting linear functions and equations

Solve word problems where you need to answer a question about a real-world relationship based on its mathematical model.

Comparing linear functions

Compare features of linear functions, such as slope and intercepts, where the functions are given in different forms—tables, graphs, or formulas.

Constructing linear models for real-world relationships

Learn how to represent real-world relationships (that are described verbally) with linear graphs, equations, or functions.

Linear models word problems

Solve general word problems about real-world relationships that can be modeled by linear equations or functions.
