keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
so we're really looking for the equation of a line whose slope is 1/2 and passes through (-4 , 1)

When you solve a proportion, your first step should be to cross-multiply.
= 
When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of x is 15.

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.
