The video tutorial explains how to identify and write function rules for linear functions using tables of data. It covers calculating the slope and y-intercept, and provides three examples of increasing complexity to illustrate the process. The tutorial emphasizes understanding the relationship between changes in x and y values to determine the linear function's equation.

What type of function is identified when there is a constant change in y for every constant change in x?

• Quadratic function

• Exponential function

• Linear function

• Logarithmic function
