The video tutorial teaches how to quantify the relationship between two proportional measures by examining graphs. It begins with an introduction to quantifying using quantities and coordinates, followed by a discussion on proportional versus non-proportional relationships. The importance of understanding graph scales is highlighted, and the tutorial concludes with methods to quantify proportional relationships using unit rates.

What does it mean to quantify a relationship?

• To describe it using numbers

• To describe it using shapes

• To describe it using sounds

• To describe it using colors

On a coordinate plane, which axis represents the independent variable?

• W-axis

• X-axis

• Y-axis

• Z-axis

What is a key feature of a proportional relationship on a graph?

• It has a curved line

• It starts above the origin

• It has a variable rate

• It starts at the origin

Why is it important to pay attention to the scale on a graph?

• Because it changes the color of the graph

• Because it changes the shape of the graph

• Because it affects the interpretation of data points

• Because it makes the graph look bigger

What happens when you change the scale on a graph?

• The data points disappear

• The data points remain the same

• The graph becomes a circle

• The interpretation of data points changes

What is the unit rate in the example of feet to yards?

• 4 to 1

• 3 to 1

• 5 to 1

• 2 to 1

In the example of chairs to tables, what is the unit rate?

• 4 chairs to 1 table

• 3 chairs to 1 table

• 5 chairs to 1 table

• 6 chairs to 1 table
