Front

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 shows the general direction of the data points.

Front

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

Back

The line of best fit can be determined by visually inspecting the scatter plot and drawing a line that minimizes the distance between the line and all the data points.

Front

What does a negative slope in a line of best fit indicate?

Back

A negative slope indicates that as one variable increases, the other variable decreases, showing an inverse relationship.

Front

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

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the y-intercept represent in a line of best fit?

Back

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

Front

What is a scatter plot?

Back

A scatter plot is a graph that displays values for typically two variables for a set of data, using dots to represent the values.

Front

What does it mean if a scatter plot shows a linear relationship?

Back

A linear relationship means that the data points can be approximated by a straight line, indicating a consistent relationship between the two variables.

Front

What is the purpose of a line of best fit?

Back

The purpose of a line of best fit is to make predictions about one variable based on the value of another variable.

Front

How can you tell if a line of best fit is accurate?

Back

A line of best fit is considered accurate if it closely follows the trend of the data points and minimizes the distance from the points to the line.

Front

What is the significance of the slope in a line of best fit?

Back

The slope indicates the rate of change between the two variables; a steeper slope means a greater change.
