2 Variable Equations

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 the variable that is tested and measured in a scientific experiment, and it is affected by the independent variable.

Front

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

Back

In the equation y = mx + b, 'm' represents the slope of the line, which indicates 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, which is the value of y when x is 0.

Front

What does the x-axis represent in a graph?

Back

The x-axis represents the independent variable in a graph.

Front

What does the y-axis represent in a graph?

Back

The y-axis represents the dependent variable in a graph.

Front

How do you determine the slope of a line on a graph?

Back

The slope of a line is determined by the rise over run, which is the change in y divided by the change in x.

Front

What is a linear equation?

Back

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

Front

What is the purpose of a table in relation to equations?

Back

A table organizes data points that can be used to identify relationships between variables and can help in forming equations.

Front

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

Back

The independent variable is usually the one that is manipulated or changed, often indicated by the question's context.
