The video tutorial explains independent and dependent variables using tables and graphs. It begins with a basic introduction to these concepts, followed by examples involving a freight train and an art class. The tutorial demonstrates how to identify these variables in real-world scenarios and how to represent them graphically. It concludes with exercises to reinforce understanding.

What is the independent variable in the freight train example?

• Miles

• Speed

• Distance

• Time

In the freight train example, what type of relationship exists between time and distance?

• Subtractive

• Additive

• Divisive

• Multiplicative

In the art teacher's clay example, what is the independent variable?

• Amount of clay available

• Amount of clay bought

• Number of students

• Class duration

What type of relationship is illustrated in the art teacher's clay example?

• Additive

• Subtractive

• Divisive

• Multiplicative

How is the independent variable typically represented in a graph?

• In the title

• In the legend

• On the horizontal axis

• On the vertical axis

In the example of Gina's savings, what does the independent variable represent?

• Interest rate

• Total expenses

• Number of days

• Amount of savings

What is the dependent variable in the example of eggs in cartons?

• Size of cartons

• Weight of eggs

• Number of cartons

• Number of eggs

In the example of DVDs, what is the independent variable?

• Number of DVDs bought

• Total DVDs owned

• DVD rental duration

• Price of DVDs

What is the key difference between the train and clay examples in terms of units?

• No units involved

• Same units for both variables

• Different units for both variables

• Units are irrelevant

How can you identify the dependent variable in a real-world graph?

• It is on the horizontal axis

• It is in the title

• It is on the vertical axis

• It is in the legend
