Sagot :

Given the following question:

The scale factor is multiplication, we are already given the before and after of the mutiplication all we have to do is find, what were the points multplied by to equal the last endpoints.

Using the process of elimination:

Option A:

[tex]\begin{gathered} 1\times\frac{1}{8}=\frac{1}{8} \\ 4\times\frac{1}{8}=\frac{1}{2} \\ 2\times\frac{1}{8}=\frac{1}{4} \\ 8\times\frac{1}{8}=1 \\ \text{Using cross mutiplication} \end{gathered}[/tex]

Your answer is option A.
