Exploring Linear Rules and Functions

This video tutorial covers linear equations, their graphing using slope-intercept form, and the concept of linear functions. It explains how arithmetic sequences relate to linear equations and how to identify functions. The tutorial also demonstrates creating rules for linear equations using slope and y-intercept, and discusses domain and range. The video concludes with a summary of key points.

• The sum of all terms

• The difference between consecutive terms

• The first term of the sequence

• The product of all terms
