Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

What is the y-intercept of a linear function?

Back

Front

What does a positive slope indicate about a linear function?

Back

A positive slope indicates that as the value of x increases, the value of y also increases, resulting in an upward slanting line.

Front

What does a negative slope indicate about a linear function?

Back

A negative slope indicates that as the value of x increases, the value of y decreases, resulting in a downward slanting line.

Front

What is an undefined slope?

Back

An undefined slope occurs in a vertical line where the change in x is zero, meaning the line does not rise or fall.

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

What is the correlation coefficient?

Back

The correlation coefficient is a statistical measure that describes the strength and direction of a relationship between two variables, ranging from -1 to 1.

Front

What does a strong positive correlation mean?

Back

A strong positive correlation means that as one variable increases, the other variable also increases significantly.

Front

What does a strong negative correlation mean?

Back

A strong negative correlation means that as one variable increases, the other variable decreases significantly.
