Graphing Equations Using the T-Table Method

The video tutorial demonstrates how to graph an equation using the T table method. It begins by explaining the selection of X values near the origin and then shows how to substitute these values into the equation to solve for Y. The tutorial covers calculations for X values of -1, 0, and 1, resulting in ordered pairs. Finally, it illustrates how to plot these pairs on a graph and connect them to form a line.

What is the purpose of using a T-table in graphing equations?

• To find the slope of the line

• To calculate the area under the curve

• To organize X and Y values for graphing

• To determine the intercepts of the graph
