Question

question #7 g.gsr.3.3 which of the following transformations was applied to figure mpsr to create figure mpsr? a. reflection over the y - axis b. rotation 270° counterclockwise about the origin c. reflection over the line y = x d. rotation 90° counterclockwise about the origin

Explanation:

Step1: Recall transformation rules

Reflection over y = x swaps x - and y - coordinates.

Step2: Observe the figure

Points in MPSR and M'P'S'R' show swapped x - y coordinates.

Step3: Eliminate other options

a. Reflection over y - axis changes sign of x - coordinate only. b. 270° counter - clockwise rotation has (x,y)→(y, - x). d. 90° counter - clockwise rotation has (x,y)→( - y,x). None match the figure transformation.

Answer:

c. Reflection over the line y = x
