Graphing a linear equation in slope intercept form

The video tutorial explains how to graph a linear equation in slope-intercept form. It begins by identifying the slope and Y-intercept, then demonstrates how to plot the Y-intercept on a graph. The tutorial continues by explaining the concept of slope as a ratio of change in Y over change in X, and how to use it to find additional points on the graph. Finally, it shows how to draw the line through the points and extend it in both directions, emphasizing that only two points are needed to define the line.

What does the graph represent in terms of points lying on the line?

Explain how the graph continues indefinitely in both directions.
