Graphing Proportional Relationships

The video tutorial introduces graphing proportional relationships, starting with the equation y=2x. It explains how to create a table of x and y values, plot ordered pairs on a graph, and understand the significance of graph quadrants. The tutorial concludes with graphing another proportional relationship, y=3/4x, demonstrating the process of creating a table and plotting points to form a straight line.

What is the equation used to represent the proportional relationship in the video?

• y = 2x

• y = x + 2

• y = x - 2

• y = 2/x
