Using technology such as excel, the linear regression equation which best models the data is y = 0.31x + 0.12

To model the data, we could use a linear regression calculator or excel which gives the slope intercept equation of the model in the form :

  • y = bx + c

Where ;

  • Slope, b = 0.31 ; intercept, c = 0.12

Therefore, the linear regression function which nest models the data in the table is y = 0.31x + 0.12
