Identifying Linear and Nonlinear Graphs and Equations

The video tutorial explains how to identify linear and non-linear graphs and equations. It begins by discussing the characteristics of linear functions, which form straight lines, and contrasts them with non-linear functions, which do not. The tutorial then delves into linear equations, highlighting common forms such as y = mx + b and ax + by = c. Key properties of linear equations are discussed, including the requirement that the largest exponent must be 1, x and y must be in separate terms, and both must be in the numerator. The video concludes with practical examples of identifying linear and non-linear graphs and equations.

Explain why the equation y = 2 divided by x is considered non-linear.
