Graphing a horizontal line by using a table of values

The video tutorial explains how to graph the equation Y = -2. It begins by discussing the slope-intercept form, Y = MX + B, and notes the absence of an X variable, indicating a slope of zero. The tutorial then explores using a table of values, emphasizing that Y remains constant at -2 for any X value. Finally, it demonstrates that the graph of Y = -2 is a horizontal line.
