Understanding the Relationship Between Independent and Dependent Variables

This lesson explains the relationship between independent and dependent variables using equations. It uses a real-world example of selling strawberry jam to illustrate how the number of jars sold (independent variable) affects the amount of money earned (dependent variable). The lesson demonstrates this relationship through equations, function tables, and graphs, emphasizing that the dependent variable is affected by changes in the independent variable. Common misunderstandings about these relationships are also addressed.

In the scenario where Carlie sells jars of jam, which variable is considered independent?

• The amount of money earned

• The total sales revenue

• The number of jars sold

• The price per jar

What does the coefficient in the equation 5j = m represent?

• The total number of sales

• The price of each jar

• The number of jars sold

• The total amount of money earned

How does the function table help in understanding the relationship between variables?

• It calculates the price per jar

• It organizes values to show how the dependent variable changes with the independent variable

• It shows the total sales revenue

• It predicts future sales

On a graph, where is the independent variable typically represented?

• In the legend

• On the x-axis

• On the z-axis

• On the y-axis

What is a common misconception about the relationship between independent and dependent variables?

• The independent variable affects the dependent variable

• The dependent variable affects the independent variable

• Both variables are independent

• Both variables are dependent
