Question

the parallelogram tuvw is a dilation of the parallelogram tuvw. what is the scale factor of the dilation?
simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.

Explanation:

Step1: Identify corresponding points

Choose point $T(-2, 0)$ and its image $T'(-10, 0)$

Step2: Calculate scale factor

Scale factor = $\frac{\text{Image coordinate}}{\text{Original coordinate}}$
$\text{Scale factor} = \frac{-10}{-2} = 3$
Verify with another point: $U(1,1)$ and $U'(5,5)$, $\frac{5}{1}=3$

Answer:

$3$
