This video tutorial covers the concept of non-proportional linear relationships, focusing on how to represent them using tables and graphs. It explains the difference between proportional and non-proportional relationships, emphasizing that non-proportional relationships do not pass through the origin. The tutorial provides a step-by-step example of graphing the equation y = 3x + 6, including selecting x-values, calculating corresponding y-values, and plotting these points on a graph. The video concludes with a review of plotting techniques and understanding graph features like the y-intercept and slope.

What does it mean for a relationship to be non-proportional?

• It has a constant rate of change and goes through the origin.

• It does not go through the origin and is not a direct variation.

• It is a curved line on a graph.

• It has a multiplicative relationship.

What is the first step in graphing a non-proportional linear equation?

• Find the y-intercept.

• Pick five x-values.

• Draw the coordinate plane.

• Calculate the slope.

Why is it important to pick x-values close to the origin when graphing?

• To ensure the line goes through the origin.

• To avoid large numbers on the graph.

• To make calculations easier.

• To make the graph look symmetrical.
