Question

Miguel says that to create rectangle F' he reflected rectangle F across the y-axis, dilated the reflection by a scale factor of 3, and translated the dilated figure to the right 2 units.

What mistake did Miguel make in describing the steps of his transformation?
A. He gave the incorrect scale factor.
B. He named the incorrect axis of reflection.
C. He gave the incorrect direction of translation.
D. He gave the incorrect number of units of translation.

Answer 1

the answer is A

Explanation:

Miguel gave an incorrect scale factor. The shape decreased in size meaning it would have a scale factor under 1 but he put 3 meaning the shape got larger when really it shrunk. This means A is the correct answer

Answer 2

A. He gave the incorrect scale factor.

Explanation:

The scale factor is the Multiplicative Inverse of 3, which is ⅓:

F → 12 × 6

F' → 4 × 2

This is a genuine statement because according to the graph, each block is worth 2, and ⅓ of 6 is 2, and ⅓ of 12 is 4.
