Question

Triangle XYZ was dilated using the rule DO,0.25 (x, y) → (0.25x, 0.25y). The image is shown in the diagram. What are the coordinates of Z of the pre-image? (–8, –4) (–8, 2) (–2, –1) (–0.25, –0.5)

Answer 1

I was able to find the image associated with this question, in which the coordinates of point Z are given as (-2,-1).

We know that the coordinates of a point are multiplied by the scale factor to give the new coordinates. Since these coordinates result after the dilation, we divide them by the scale factor to obtain the original coordinates as such:

-2/0.25 , -1/0.25

(-8 , -4)

Answer 2

Answer:

(-8, -4)

I hope this helps!
