Independent vs Dependent Variables

Front

What is an independent variable?

Back

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable. It is often represented by 'x' in equations.

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured or tested in an experiment. It is affected by changes in the independent variable and is often represented by 'y' in equations.

Front

In the equation y = x - 3, what is the independent variable?

Back

The independent variable is x.

Front

In the equation y = x - 3, what is the dependent variable?

Back

The dependent variable is y.

Front

What does the ordered pair (7, 8) represent?

Back

In the ordered pair (7, 8), 7 is the x-coordinate (independent variable) and 8 is the y-coordinate (dependent variable).

Front

If x = 5 in the equation y = x - 3, what is the value of y?

Back

y = 5 - 3 = 2.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe how it affects the dependent variable.

Front

In a graph, which axis typically represents the independent variable?

Back

The x-axis typically represents the independent variable.

Front

In a graph, which axis typically represents the dependent variable?

Back

The y-axis typically represents the dependent variable.

Front

If the independent variable increases, what can happen to the dependent variable?

Back

The dependent variable may increase, decrease, or remain constant, depending on the relationship defined by the equation.
