The video tutorial focuses on interpreting graphs in word problems, specifically in the context of Q14. It provides three examples: Diana's spools of thread, Nicole's hair bands, and Kathleen's walking distance. Each example demonstrates how to read and interpret graphs by identifying inputs and outputs. The tutorial emphasizes the importance of understanding the axes and the relationship between variables. It concludes with tips on carefully reading the language used in word problems to accurately interpret the graphs.

What does the x-axis represent in the graph related to Diana's spools of thread?

• Amount of money spent

• Total distance walked

• Number of spools of thread remaining

• Number of dresses sewn
