Question

What scale factor was used to dilate STUV to S’T’U’V?

A. 0.20
B. 0.50
C. 0.25
D. 0.75

Answer 1

Answer: C. 0.25

Step-by-step explanation:

Large Shape: S (-4, 12)   T (2, -4)    U (6, -8)   V (-12, -8)

Small Shape: S (-1, 3)   T (0.5, -1)    U (1.5, -2)   V (-3, -2)

For the smaller shape the distance between V and U is 4.5

For the larger shape the distance between V and U is 18

So when you divide $\frac{4.5}{18}$ you should get 0.25

S: $\frac{-4}{-1}=4$     $-4 *0.25=-1$

T: $\frac{2}{0.5}=4$     $2*0.25=0.5$

U: $\frac{6}{1.5}=4$     $6*0.25=1.5$

V: $\frac{-12}{-3} =4$    $-12*0.25=-3$

I hope this helps
