Graphing and Characteristics of Linear Functions

This video tutorial introduces linear functions, explaining how to identify them through graphs, ordered pairs, and equations. It covers the vertical line test for graph identification, the concept of constant change in ordered pairs, and the standard form of linear equations. The tutorial concludes with a demonstration of graphing linear functions using two points.

What is a key characteristic of a linear function when represented on a graph?

• It forms a straight line.

• It forms a curved line.

• It forms a zigzag pattern.

Which test can be used to determine if a graph represents a function?

• Vertical line test

• Diagonal line test

• Horizontal line test

• Curved line test
