Function Tables and Ordered Pairs

The video tutorial explains how to graph linear equations using function tables. It begins with an introduction to function tables, also known as input-output tables, and their role in graphing equations. The tutorial then demonstrates graphing the equation y = x + 2 by assigning values to x and calculating corresponding y values to plot points on a graph. The process is repeated for the equation y = 2x + 1, showing how to plot points and draw the line representing the equation. The video emphasizes using whole numbers for simplicity and ensuring points fit on the graph.
