Identifying Linear Functions and Graphs

The video tutorial explains how to identify linear functions using three methods: graphs, points, and equations. It covers the characteristics of linear functions, such as passing the vertical line test for graphs, having constant changes in x and y values for points, and ensuring variables are not multiplied, squared, or in denominators for equations. The tutorial concludes with encouragement to continue practicing math skills.

What does it mean if a graph passes the vertical line test?

• It is a linear function

• It is a non-linear function

What is the result of a vertical line intersecting a graph more than once?

• The graph is linear

• It indicates a logarithmic function

What is the result of a graph failing the vertical line test?

• The graph is non-linear

• The graph is linear
