Question

The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (−3,−2). What is the scale factor used to create the dilation?

Answer 1

-1/4

Explanation:

The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (−3,−2).

The length of the base of larger triangle is 8 units

The base is reflected with center (-3,-2). the length becomes 2 units

The length of larger triangle is 8 units . the length of smaller triangle is 2 units.

8 units then become 2 units

scale factor = x

8*x = 2 so x=2/8

reduced is 1/4

However, since the image is flipped like that, then the answer must be negative. Making it -1/4.

Answer 2

Try this option:

Scale_factor (s_f) is new_size:initial_size:

s_f=8/2=4

answer: 4
