Graphing Linear Equations Using Tables of Values

This video tutorial covers graphing linear equations, including creating tables of values, plotting ordered pairs, and using graphs to solve real-life problems. It demonstrates graphing equations like y = x + 1 and y = -2x + 1, and explains how to graph horizontal and vertical lines. The tutorial concludes with a real-life application, using a graph to determine when a tropical storm becomes a hurricane based on wind speed.
