Marcus suggests that figure A was reflected over the y-axis and then translated 2 to the right and 1 up. Julianne agrees and states that the transformations could happen in any order. Which best describes the accuracy of Julianne’s statement?
A) Accurate. A translation of figure A of 2 to the right and 1 up and then a reflection over the y-axis produces the image, figure B.
B) Accurate. A reflection over the y-axis and then a translation of 1 up and 2 to the right produces the image, figure B.
C) Inaccurate. A translation of 2 to the right and 1 up and then a reflection over the y-axis results in a figure that is located in the second quadrant.
D) Inaccurate. A reflection over the y-axis and then a translation of 1 up and 2 to the right results in a figure that is located in the second quadrant.
