Comparing Linear Functions in Various Forms

The video tutorial explores the properties of linear functions presented in different forms: graph, table, equation, and description. It guides viewers through determining the steepest function by comparing slopes, identifying functions with y-intercepts greater than -3, and finding the y-intercept farthest from zero. The tutorial emphasizes understanding slopes and y-intercepts in various representations to answer related questions effectively.

What is the primary characteristic of a linear function?
