Answer:

See below.

Step-by-step explanation:

OB = OA + AB

AB = OB - OA

= 4x + 8y - (2x + 9y)

= 2x - y

CD = 4x - 2y

= 2(2x - y)

Therefore the vector CD has the same direction as AB (its the same line on the coordinate plane) but has twice the magnitude of AB. That is its represented by a line twice as long.).

The scale factor is:
$6,75/4,5 = 9/6 = 1,5$

So you divide the corresponding lengths and the ratio you get is the scale factor. Hope it helps!
