Answer:

The scale factor is
(1)/(2)

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


z=(DE)/(AB)

we have

observing the graph


DE=4\ units


AB=8\ units

substitute


z=(4)/(8)=(1)/(2)

The scale factor is less than one

therefore

Is a reduction
