Graphing Linear Equations and Systems

The video tutorial covers solving systems of linear equations using graphs and tables. It begins with an introduction to the topic, followed by a word problem involving bikes and trikes. The tutorial then explains how to graph linear equations using slope-intercept form and solve systems using tables, illustrated with shark growth rates. Finally, it discusses classifying systems of equations as independent, dependent, or inconsistent.
