Two Variable Relationships

Front

What is a two-variable relationship?

Back

A relationship that involves two variables, where the value of one variable depends on the value of the other.

Front

What does the equation y = x - 2 represent?

Back

It represents a linear relationship where the value of y is 2 less than the value of x.

Front

What does the equation y = 2x represent?

Back

It represents a linear relationship where the value of y is twice the value of x.

Front

What is an independent variable?

Back

The variable that is manipulated or changed in an experiment, often represented on the x-axis.

Front

What is a dependent variable?

Back

The variable that is measured or observed in an experiment, often represented on the y-axis.

Front

How do you identify independent values in a data set?

Back

Independent values are the input values that are controlled or set in an experiment, often listed in a sequence.

Front

What is the slope of a line in a graph?

Back

The slope indicates the steepness of the line and represents the rate of change between the two variables.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as one variable increases, the other variable also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

What is the y-intercept in a linear equation?

Back

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