I don't know if this is what you needed but i hope it helps :)
Scale factor is equal to 1/2, since the point went from 10 to 5
Given:
The function is

To find:
The vertical asymptote of the given function.
Solution:
Vertical asymptote are the vertical line passes thought the values for which the function is not defined.
To find the vertical asymptote, equate the denominator equal to 0.
We have,

Denominator is (x+2).


The vertical asymptote is
.
Therefore, the correct option is B.
