I say 28.3, which is the value of y when x=0

y=28.26+0.486*x

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

here I use standard deviation = 0.2316
range of interval= 0.2316*1.96= 0.454
