Graphing a linear equation from a table

The video tutorial explains how to graph linear equations using a table. It begins with setting up the XY axis and plotting coordinate points. The instructor demonstrates how to plot points such as (-2, 2) and (0, -4) on the graph. The tutorial then shows how to connect these points to form a straight line, emphasizing that the line extends indefinitely. The video concludes by identifying the Y intercept at (0, -4) and estimating the X intercept between -2 and -1.

What does it mean when the graph continues indefinitely in both directions?

How can you find the X intercept based on the information given?
