6.EE.9 Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is a variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is a variable that depends on the independent variable. It is what you measure in the experiment.

Front

In the equation y = 30x, which variable is independent?

Back

x is the independent variable.

Front

In the equation s = 50 + 20w, what does 's' represent?

Back

s represents Peter's total money after babysitting for 'w' weeks.

Front

What does the term 'relationship' mean in the context of independent and dependent variables?

Back

A relationship describes how one variable affects another variable.

Front

If the number of tickets (t) is the independent variable, what is the dependent variable in a ticket pricing scenario?

Back

The dependent variable could be the total cost (c) of the tickets.

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying these variables helps to understand how changes in one variable affect another.

Front

How can you identify the independent variable in a word problem?

Back

Look for the variable that is being manipulated or changed.

Front

What is the formula for a linear relationship?

Back

The formula for a linear relationship is typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

In a graph, how can you tell which variable is independent?

Back

The independent variable is usually plotted on the x-axis.
