The video tutorial explains how to identify linear functions by plotting ordered pairs on a coordinate plane and analyzing their alignment. It covers determining the slope and correlation of points, whether positive or negative, and discusses how to identify linear patterns even when points are not equally spaced. The tutorial also demonstrates how to find outputs from given inputs on a graph and determine the slope direction. The video concludes with examples of both linear and non-linear functions.
