An image point of a transformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(6, -12), what was the transformation and scale factor?

reflection with scale factor 3
reflection with scale factor 1/3
dilation with scale factor 3
dilation with scale factor 1/3

Respuesta :

Answer:

Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3

Step-by-step explanation:

i) the pre-image co-ordinates is  Y(6, -12)

ii) the coordinates of the image is Y' (2, -4)

iii) therefore we can clearly see that if we divide the coordinates of the pre-image (6,-12) by 3 then we get the coordinates of the image(2,4).

Therefore this is a dilation with scale factor of 1/3.

Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3

answer:

the answer is dilation with scale 1/3
