### Display Y-intercept?

I was able to successfully compute the following with Sage ~~5.9:
~~5.9:

`p1 = `~~plot(20~~*x **plot(20*x + 10000, -8,600, ymin = -15, ymax = 30000)
p2 = *~~plot(80~~x, plot(80*x, -8,600, ymin = -15, ymax = 30000, color = 'orange')
p9 = (p1 + p2)
~~plot(p9)~~plot(p9)

Is it possible for me to get Sage to display the point of intersection between the 2 lines?

The intersection occurs at 166 of the x-axis, with a y value of around 13300.
