Using the standard linear regression relation :

y = bx + c

b slope ; c = intercept ; y = dependent ; x = independent variable.

For finalist between 2004 - 2014 ;

y = 0.024x - 0.328

x = 35

y = 0.024(35) - 0.328

y = 0.512

For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :

y = -0.015x - 0.328

x = 14.

y = -0.015(14) - 0.328

y = - 0.538
