Question: plot and smartplot together in one

Hi

I have two sets of plots

1. plot([1 - 2*x, -0.6 - 2*x, -1 - 2*x], x = -1 .. 1)

2. smartplot[x, y](map('`=`', [31*y^2 + 0.19*x^2 + 0.34*x*y - 0.38*y - 0.22*x + 0.07, 0.31*y^2 + 0.19*x^2 + 0.34*x*y - 0.38*y - 0.22*x, 0.31*y^2 + 0.19*x^2 + 0.34*x*y - 0.38*y - 0.22*x + 0.02, 0.31*y^2 + 0.19*x^2 + 0.34*x*y - 0.38*y - 0.22*x + 0.07, 0.31*y^2 + 0.19*x^2 + 0.34*x*y - 0.38*y - 0.22*x + 0.11], 0))

How do i combine the two into one plot?

thanks!
