Line of Best Fit
Algebra 1 · Exponential Functions & Data
Definition
A line of best fit is a straight line drawn through scatter plot data to model its overall trend.
Examples
- A best-fit line through study data predicts grades.
- Draw the line so points are balanced above and below.
Key rule
The line of best fit models the trend, not every point.
Memory hook
Best-fit line = the trend line through the cloud.
