What does the slope of a line represent?

Back

The slope of a line 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 a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot. It minimizes the distance between the line and all the points in the dataset.

What does a positive correlation indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also increases. The points on a scatter plot tend to rise from left to right.

Front

What does a negative correlation indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases. The points on a scatter plot tend to fall from left to right.
