# MTH 219 Week 2 Introductory & Intermediate Algebra for College Students, Ch. 3, Sections 3.1 & 3.3: Linear Equations in Two Variables

## In Ch. 3 you continue to learn about graphs of linear equations. You explore how graphs are created and continue to expand your mathematical vocabulary. An important part of graphing that this reading covers is how to determine the rate of change from a graph using the slope.

- View one of the following Week 2 videos:
- Khan Academy’s “What is a function“

- Patrick Just Math Tutorials: “The Vertical Line Test“

- Khan Academy’s “Evaluating a Function: Formula“

- Khan Academy’s “Evaluate a Function: Graph“

What are the various ways of representing a function? What methods can you use to determine whether a relation is a function? Give an example of a relation and determine if it is a function.
