Question

the square vwxy is a dilation of the square vwxy. 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: Find side length of VWXY

Take points $W(-2,2)$ and $X(-2,0)$. Side length $= |2-0| = 2$.

Step2: Find side length of V'W'X'Y'

Take points $W'(-3,3)$ and $X'(-3,0)$. Side length $= |3-0| = 3$.

Step3: Calculate scale factor

Scale factor $= \frac{\text{Image side length}}{\text{Pre-image side length}} = \frac{3}{2}$.

Answer:

$\frac{3}{2}$
