How do I do this?
I've got to (2+3lambda)i + (5-lamda)j
I've got to (2+3lambda)i + (5-lamda)j
If that is parallel to i how much j will there be?

Wouldn't they be the same?

If you imagine the vector i. Its horizontal to the x axis. So for a+λb to be parallel to i, the j component of your equation must equal 0, so a+λb is "parallel" to the x axis.

I don't understand this properly, does anyone have something which explains it?
If pi + qj is parallel to mi + nj
Then p = km and q= kn
Original post by TenOfThem
If pi + qj is parallel to mi + nj
Then p = km and q= kn
Then p = km and q= kn
How have you got that?
if pi is parallel to mi then mi must be a factor of pi?

Yes but more than that
If mi + qj is parallel to ni
What do you know about q

If mi + qj is parallel to ni
What do you know about q
q=0
Original post by zed963
q=0
Can you apply that to your original question
