Similar to reading from a file, except you open the file for "w" (write)
instead of "r" (read):
f = open("menu","w")
f.write("spam, spam, spam and eggs\n")
f.write("spam, eggs, spam, spam, bacon and spam\n")
You can also open it "a" to append to a file (if you open for write, the
first thing that happens is that the old file is emptied, if it exists).

I'm not sure what the y-intercept is. You mean the point in the middle of
those two? That's just the average point, ie ((x1+x2)/2, (y1+y2)/2).
