What is a dependent variable?

Back

A dependent variable is the variable that is being measured or tested in an experiment. It depends on the independent variable.

Front

What is an independent variable?

Back

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

Front

How do you write a function rule from a table?

Back

To write a function rule from a table, identify the relationship between the input (x) and output (y) values, and express it as an equation.

Front

What does the equation y = mx + b represent?

Back

This is the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input.

Front

What does it mean for a variable to be independent?

Back

An independent variable is one that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

How do you determine the function from a set of data points?

Back

To determine the function, look for patterns in the data points and try to express the relationship as an equation.

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function creates a straight line when graphed, while a non-linear function creates a curve.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.
