Graphing Linear Equations and Functions

The video tutorial explains how to graph equations of the form x = 2 and y = 3. It demonstrates that x = 2 results in a vertical line with an undefined slope, while y = 3 results in a horizontal line. The tutorial uses tables to illustrate these concepts and discusses the slope-intercept form for better understanding.
