What is the independent variable in a function?

Back

The independent variable is the variable that represents the input of a function, which can be changed freely.

What is the dependent variable in a function?

Back

The dependent variable is the variable that depends on the value of the independent variable; it is the output of the function.

What does it mean to write an equation?

Back

Writing an equation means creating a mathematical statement that shows the equality between two expressions.

Front

What is the y-axis on a graph?

Back

The y-axis is the vertical line on a graph that typically represents the dependent variable.

Front

What is the x-axis on a graph?

Back

The x-axis is the horizontal line on a graph that typically represents the independent variable.

Front

How do you identify the dependent variable from a word problem?

Back

The dependent variable is usually the outcome that changes based on the independent variable.

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 does 'm' represent in the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope of the line, indicating how steep it is.

Front

What does 'b' represent in the equation y = mx + b?

Back

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