Speaking of which, Li-sa seems to have disappeared after leaving that mysterious truncated comment. Could she have been trapped in a recurrent time warp like what happened to Miss Loi awhile ago?

]]>1. 3a-4b

Pretty straightforward to form the triangle consisting of 3 units of vector `a` and 4 units of `b`. Looking at the direction of the arrows, you can see that

3`a` = + 4`b`

⇒ = 3`a` - 4`b`

2. Q:(F,3)

Shifting `a` and `b` to form a triangle with a point at `O` (since we're finding so one end *has* to be at `O`) we can then locate `Q` to be a (F, 3).

3i. R:(D,3)

ii. h=3, k=-1

Now, which means that is parallel to (from the Scalar Multiple portion of the notes above). Furthermore, since there's a common point `O` this means that `R` must lie somewhere along grid-line #3.

= `k``b` means that has to be parallel to `b`. And with the vector originating from point `P`, this means that `R` must lie somewhere along grid-line #D.

So from this info, we can locate `R` at (D, 3) in the grid.

And looking at the diagram,

is three times longer than and in the same direction ⇒ `h` = 3

is the same length as `b` and in the same direction ⇒ `k` = 1

**Care to share how you got k = -1 in your answer when is in the SAME DIRECTION as b???** *scratch head*
