											Answer:
The scale factor is [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and is called the scale factor
Let
z------> the scale factor
so
[tex]z=\frac{DE}{AB}[/tex]
we have
observing the graph
[tex]DE=4\ units[/tex]
[tex]AB=8\ units[/tex]
substitute
[tex]z=\frac{4}{8}=\frac{1}{2}[/tex]
The scale factor is less than one
therefore
Is a reduction
