>> LINE OF BEST FIT MODELING
Master visual trend line fitting, linear equations (y = mx + b), and predictive extrapolation for Grade 8 statistics.
1. Line of Best Fit
A straight line drawn through data points that best expresses the relationship between variables.
2. Linear Equation (y = mx + b)
Find the slope (m = rise / run) and y-intercept (b) of the trend line.
3. Prediction Modeling
Substitute target input values into the linear model to solve for unknown quantities.
