Triangle ABC has Points A, B, and C located at (3, 6), (−2, 2), and (6, −4), respectively. Triangle DEF is a dilated image of Triangle ABC. Point D is located at (9, 18). What is the scale factor for the dilation of Triangle ABC?

1 : 1

1 : 3

2 : 1

3 : 1

b

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
