How do you write an equation for line of best fit? - Answers

To write an equation for a line of best fit, first plot your data points on a scatter plot. Then, use statistical methods like least squares regression to determine the slope (m) and y-intercept (b) of the line. The equation will be in the form of ( y = mx + b ), where ( y ) is the dependent variable, ( x ) is the independent variable, and ( m ) and ( b ) are calculated based on your data. Finally, you can use software or a calculator to help with the calculations if needed.
