Suppose a 2D line passes through two points P0(10, 15) and P1(200, 20). Answer Questions 7 *- 10 regarding this line.
Question 7) Which of the following vectors parallel to the line?
(180, *10)
(190, 5)
(*380, *10)
(*180, 10)
I AM NOT WANTING AN ANSWER. I am hoping someone can take some time to explain to me how to work this out. I have searched online around this topic, and havent seemed to find much unless I am searching the wrong thing. I know this is about placement lines in vectors. So far what I think is I am meant to draw a 200x200cm grid, plot all the answers and see what is parallel to the two points P0(10, 15) and P1(200, 20)?
All explanations and help is much appreciated.
You don't need to draw a 200x200 grid.... Just find what the vector from P0 to P1 is and take the answer which is a multiple of it.
