  2. <python111> saraw, they don't lay on the same line, but can determine same line
  3. <python111> how you put them, they don't lay on the same line
  4. <python111> but when you say a = 2i - 2j, it's just vector that has beginning in O, and end in (2, -2)
  5. <python111> so it doesn't matter where you put it.
  6. <python111> set of all same lines that have same directions and lengths is called a vector
  7. <python111> what you've drawn are representants of this same vector
  8. <vladsot> vectors are not arrows; vectors are translations and arrows represent translations.
  9. <python111> saraw, but if you want to say: this line which starts at (0,0) is p1 and which starts at (2,1) is p2, those 2 lines are different
  10. <python111> depends on vectors again now
  11. <oriig> Rashad, you may want to take a look at google's pagerank
  12. <python111> if you use the vectors you've calculated, then yes
  13. <python111> this vector: x = 2i - 2j that you've obtained, if you put it in O -- different line than the same vector put in (2,1)
  14. <python111> that's what you say by an equation: put the starting point here along this vector
