Linear Graphs and Value Tables

This video tutorial explains how to complete a table of values for a linear graph by substituting x values into a given equation to find corresponding y values. It demonstrates the process using examples, highlights patterns in the y values, and explains how these patterns relate to the equation. The tutorial also covers calculations involving negative x values, reinforcing the understanding of linear relationships.
