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
