This can be done with CoefficientList. For example,

In[1]:=
data = Table[n + Random[], {n, 10}]; 
m = Fit[data, {1, x}, x]

Out[2]=
0.9611100607503279*x + 0.6369661439363206

In[3]:=
CoefficientList[m, x]

Out[3]=
{0.6369661439363206, 0.9611100607503279}

But rather than using Fit, you could use FindFit and immediately get a list of the coefficients, i.e.,

In[4]:=
FindFit[data, a*x + b, {a, b}, x]

Out[4]=
{a -> 0.9611100607503279, b -> 0.636966143936322}
