Graphing Linear Equations through Coordinate Tables

The video tutorial explains how to graph the linear equation y = 2x + 3. It begins by introducing the concept of graphing linear equations and setting up a table of coordinates. The instructor chooses x-values and calculates corresponding y-values to form coordinates. These coordinates are then plotted on a graph, with scales set for both axes. The points are connected to illustrate the linear pattern, and the graph is verified for accuracy. The tutorial concludes by encouraging viewers to explore more math resources.
