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.
