Line of Best Fit Review

Front

What is a line of best fit?

Back

A line that best represents the data on a scatter plot, showing the trend of the data points.

Front

What does a positive linear association indicate in a scatter plot?

Back

As one variable increases, the other variable also increases.

Front

What does a negative linear association indicate in a scatter plot?

Back

As one variable increases, the other variable decreases.

Front

What is a nonlinear association?

Back

A relationship between two variables that does not follow a straight line.

Front

How can you identify a linear relationship in a scatter plot?

Back

The data points will form a pattern that can be approximated by a straight line.

Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line of best fit represent?

Back

The rate of change between the two variables.

Front

What is the y-intercept in the context of a line of best fit?

Back

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

Front

How do you determine the line of best fit using a scatter plot?

Back

By visually assessing the data points and drawing a line that minimizes the distance to all points.

Front

What is the purpose of a line of best fit?

Back

To make predictions about one variable based on the value of another variable.
