This video tutorial covers 8th grade math concepts from illustrative mathematics unit 6, lesson 8. It begins with an introduction to scatter plots, discussing how to draw them and identify outliers. The video then explores different types of associations in scatter plots, such as linear, non-linear, and positive associations. Finally, it analyzes the slope of scatter plots, explaining how to determine if a slope is positive, negative, or zero. The video concludes with a call to action for viewers to subscribe and watch the next lesson.

What is the horizontal axis labeled in the scatter plot for book sales data?

• Number of books sold

• Price in dollars
