The sum of the median x values is 206.5, and the sum of the median y values is 476. Substituting these sums and the slope into the formula gives b = 476 − 6.9 ( 206.5) 3 , which simplifies to b ≈ − 316.3 . The line of best fit is represented as y = m x + b . Thus, the equation can be written as y = 6.9 x − 316.3.A linear regression lets you use one variable to predict another variable’s value. Regression line formula.
