Question

Plzz help i need accurate answers plzz ill fan! :)
The triangle 𝐴𝐵𝐶 has coordinates 𝐴=(-6,1), 𝐵=(-5,4), and 𝐶=(6,-7). The triangle is dilated from the origin by a scale factor 𝑟 = 3. Identify the coordinates of the dilated triangle 𝐴′𝐵′𝐶’.

a) A’ = (-18, 3), B’ =(-15,12),C’ = (-18, 21)

b) A’ = (-18, 3), B’ =(-15,12), C’ = (18, -21)

c) A’ = (18, 3), B’ =(-15,-9), C’ = (18, -21)

d) A’ = (-18, -3), B’=(-15,12), C’ = (-18, 21)

Answer 1

Dilations just mean that we are scaling the coordinates by a number. In this case, the scale factor is 3, so we just simply multiply all the coordinates by 3.

Answer 2

For example,
A = (-6, 1)
A' = 3 x (-6, 1) = (-18, 3)

Answer 3

so what the answer a b c or d ??
sorry i need exact answers :)

Answer 4

I already found A' for you, now try to find B' and C' yourself. You should then be able to get the answer.

Answer 5

B' = 3 x (-5, 4)
C' = 3 x (6, -7)
