An image point of a transformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(8, -16), what was the transformation and scale factor? A. dilation with scale factor 1/4 B. dilation with scale factor 4 C. reflection with scale factor 1/4 D. reflection with scale factor 4
The answer is B. dilation with scale factor 4 Hope it helps!
Here, Magnitude is changing, so it would be: "Dilation" instead of reflection. Scale factor would be: = Image size / Object size s.f. = 2/8 = 1/4 In short, Your Answer would be: Option A Hope this helps!
