The line of best fit model the relationship between variables on a dataset

How to determine the equation?

For the line of best fit, we have the following calculation summary (from a graphing calculator)

  • Sum of X = 73
  • Sum of Y = 536
  • Mean X = 6.6364
  • Mean Y = 48.7273
  • Sum of squares (SSX) = 136.5455
  • Sum of products (SP) = 1249.9091
  • Slope (b) = 9.15
  • Y-intercept (a) = -12.02

The equation of the line of fit is represented as:

[tex]y = bx + a[/tex]

So, the equation of the line of fit is:

[tex]y = 9.15x - 12.02[/tex]
