Line of best Fit

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, showing the trend of the data points.

How do you determine the line of best fit?

Back

You can determine the line of best fit by plotting the data points on a graph and drawing a line that minimizes the distance between the line and all the points.

Front

What is the purpose of using a line of best fit?

Back

The purpose of using a line of best fit is to make predictions about data points that are not explicitly given.

What does it mean to extrapolate data?

Back

Extrapolating data means estimating a value outside the range of known data points using the line of best fit.

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.

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

Back

Slope represents the rate of change between the two variables in the data set, indicating how much one variable changes for a unit change in another.

What is a scatter plot?

Back

A scatter plot is a graph that displays two variables as points in a Cartesian coordinate system, showing the relationship between them.

How can you use a line of best fit to make predictions?

Back

You can use a line of best fit to predict unknown values by finding the corresponding y-value for a given x-value on the line.

Front

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

Back

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