Is there a way to gain the equations and coefficients when using the R's car package of both the smoothing and regression (line) model? 

scatterplot(prestige ~ income, data=Prestige)
scatterplot(prestige ~ income, data=Prestige, smoother=gamLine)

(the gamLine argument requiring the mgcv package)

Thanks

In the first case, you can see the info by

summary(lm(prestige ~ income, data = Prestige))

In the 2nd case, something similar will likely apply but I don't know that package or smoothing method. It's surely not as simple as a linear fit. Take a look at ?mgcv-FAQ.
