Independent and Dependent Variables-Math

Front

What is an independent variable?

Back

An independent variable is the 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 the variable that is measured and affected in an experiment, responding to changes in the independent variable.

In the equation y = mx + b, what does 'm' represent?

Back

In the equation y = mx + b, 'm' represents the slope of the line, indicating the rate of change of y with respect to x.

Front

In the equation y = mx + b, what does 'b' represent?

Back

In the equation y = mx + b, 'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

How do you identify the independent variable in an experiment?

Back

The independent variable is identified as the factor that is intentionally varied or manipulated by the researcher.

Front

How do you identify the dependent variable in an experiment?

Back

The dependent variable is identified as the factor that is observed and measured to see how it is affected by changes in the independent variable.

Front

What is the relationship between independent and dependent variables?

Back

The relationship is that changes in the independent variable cause changes in the dependent variable.

Front

What is the purpose of a control variable in an experiment?

Back

A control variable is kept constant to ensure that any changes in the dependent variable are solely due to the manipulation of the independent variable.

Front

What is a linear equation?

Back

A linear equation is an equation that represents a straight line when graphed, typically in the form y = mx + b.

Front

What does it mean for a variable to be 'controlled' in an experiment?

Back

To control a variable means to keep it constant and not allow it to change during the experiment.
