Find a vector 3 units long in the opposite direction from v = 〈3, 1,-4).

Unit vector along the direction v = <3,1,-4> is :

So, unit vector opposing the is :

so, vector of magnitude 3 units in opposite direction from v is :

Hence, this is the required solution.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
