It is parallel, which means that the new line should have the same slope of the given line 
and the slope is the coefficient of x
so the slope = -5/4
in order to solve this problem we have to know the equation of the slop
where (x1,y1) is the point by which the new line passes through
-5(x-1)=4(y+4)
-5x +5=4y+16 (by subtracting 16 from both sides)
-5x -11= 4y (divide both sides by 4)
y=

Note that what we want is to compress any point (a, b) in the parent function, to (a, b/4).
(a, b) is a point of the graph of the function
, thus we can rewrite the point as:
.
This point is compressed to
.
This means that the function we are looking for is
.
