Step-by-step explanation:

Answer:
here is your answer in the picture..
Answer:

Step-by-step explanation:
Look at the component form of each vector.
Note that vector c is <4,4> and vector d is <-2,-2>
If one imagined the line that contained each vector, the line for both would have a slope of 1, because 
Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).
If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector. This means that there is some number "k", such that
, or equivalently,
and
.
If
and
, we just need to substitute known values and solve for k:

Double checking that k works for the y-coordinates as well:

? 

So, 
Answer:
Option 2
Step-by-step explanation:
y=x+3 is a positive slope so the line going up to the right is a positive slope and the line passes through y-intercept at 3
Answer:
the karla question. the answer is unfair
Step-by-step explanation:
because the multiple of 3 is 6
but there is no multiple of 4
so therefore it is not fair
