Front

What does a line of best fit represent in a scatterplot?

Back

A line of best fit represents the trend of the data points in a scatterplot, showing the overall direction (increasing or decreasing) of the relationship between the variables.

What is the definition of a linear function?

Back

Front

How do you determine if a function is decreasing?

Back

A function is decreasing if, as the input values increase, the output values decrease. This can be observed in a scatterplot where the points trend downward.

Front

What is a positive correlation in a scatterplot?

Back

A positive correlation occurs when, as one variable increases, the other variable also increases, resulting in an upward trend in the scatterplot.

Front

What is the significance of the coordinates in a scatterplot?

Back

The coordinates in a scatterplot represent the values of two variables, allowing for visual analysis of their relationship.
