Graphing Linear Equations and Functions

This video tutorial explains how to graph linear equations by creating a table of values. It covers two examples: Y = X + 2 and Y = 2X - 1. The instructor demonstrates how to substitute X values into the equations to find corresponding Y values, plot these points on a coordinate plane, and connect them to form a line. The tutorial emphasizes the simplicity and effectiveness of this method for graphing linear equations.
