Exploring Vocabulary for Linear Functions

The video tutorial covers vocabulary and concepts related to linear functions, including their graphical representation as straight lines, the constant rate of change, and different equation forms like slope-intercept and standard form. It explains independent and dependent variables, and provides examples of linear equations. Key concepts such as slope, rate of change, initial value, and y-intercept are defined. The tutorial includes practical examples to calculate slope and y-intercept, reinforcing the understanding of these concepts.
