I was able to successfully compute the following with Sage 5.9: p1 = plot(20x + 10000, -8,600, ymin = -15, ymax = 30000) p2 = plot(80x, -8,600, ymin = -15, ymax = 30000, color = 'orange') p9 = (p1 + p2) 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.
