Characteristics of Linear Functions

The video tutorial covers five questions related to scientific notation, graphing points, line equations, identifying nonlinear functions, and using tables to determine linearity. Each section provides a detailed explanation of the concepts involved, including how to write numbers in scientific notation, graph points on a line, find the correct line equation, identify nonlinear functions, and use tables to check for linearity.
