here you have this function: \[y = B + Ax\]
theopenstudyowl
  • theopenstudyowl
ok
Michele_Laino
  • Michele_Laino
I say 28.3, which is the value of y when x=0
theopenstudyowl
  • theopenstudyowl
ok that make sense!
Michele_Laino
  • Michele_Laino
I think y=28.26+0.486*x

  • Michele_Laino
I think it is the subsequent ratio: \[\Large t = \frac{1}{{0.4865}}\]

I think that we have to use: 30 -2 = 28 degrree of freedom, since we have two parameters, namelythe constants A and B which appears into this formula: y = Ax+B
