Question

The triangle is an image produced by the composition Transition 4,-1 and Rotation 0,270 degrees. What are the coordinates of the preimage of vertex M?

A. (–6, –3)
B. (–3, –6)
C. (–2, 2)
D. (0, –4)

Answer 1

The answer here would be B!

Answer 2

You answer this by first rotating the image by -270 degrees about the origin. Point M will then be (2, -2). Then, apply the opposite of the transition. (2-4, -1+3). So, the preimage of vertex M is (-2,2). The answer is C.
