Dilation is either : enlargement or shirking.

Simply you multiply the ordered pair times the dilation vector (Origin-Centered)

D.F = dilation factor;

d.f = 5

C' = d.fC

when you multiply a constant times an ordered pair , it multiples into each of the pair.

C' = 5 ( -5 , 1 ) = ( -25, 5 )

In case you were asked for A' , B' (test yourself before checking)

A' = 5 (-4,3) = ( -20 , 15)

B' = 5 ( 2, 3 ) = ( 10, 15)

Dividing the dilated by the original pair results in the dilation factor

A'/A = (-20/15)/(-4,3) = 5(-4,3)/(-4,3) = 5

Answer:

$\begin{array}{lll}&\text{Statement}&\text{Reason}\\1.&WX>XY&\text{Given}\\2.&\angle 3>\angle 4&\text{angle opposite longer side is larger angle}\\3.&\angle 1=\angle 3+\angle 2&\text{exterior angle is equal to the sum of remote interior angles}\\4.&\angle 1>\angle 3&\text{If a=b+c and } c>0, \text{then } a>b\\5.&\angle 1>\angle 4&\text{transitive property}\end{array}$

Step-by-step explanation:

1. Given WX>XY.

2. Then angle 3 has larger measure than angle 4, because angle opposite longer side is larger angle. This means that

$\angle 3>\angle 4.$

3. Consider exterior angle 1. By the exterior angle theorem, the measure of the exterior angle is equal to the sum of the measures of remote interior angles. Then

$\angle 1=\angle 3+\angle 2.$
