What set of transformations are applied to parallelogram abcd to create a'b'c'd'? parallelogram formed by ordered pairs a at negative 4, 1, b at negative 3, 2, c at negative 1, 2, d at negative 2, 1. second parallelogram transformed formed by ordered pairs a prime at 4, negative 1, b prime at 3, negative 2, c prime at 1, negative 2, d prime at 2, negative 1. a) reflected over the x-axis and reflected over the y-axis b) reflected over the y-axis and rotated 180° c) reflected over the x-axis and rotated 90° counterclockwise d) reflected over the y-axis and rotated 90° counterclockwise

Let's choose a specific point/vertex on both parallelogram and see the changes; 

Observing that A is (-4, 1) and A' is (4, -1). 

From this we can observe that the graph was flipped over the x-axis because the x value went from negative to positive. Again, we see that the shape was flipped over the y-axis since the y values went from positive to negative. 

From this scenario, the correct solution should be A. 

Double check this by picking another vertex and comparing. 

D's coordinates are (-2, 1) and D' is (2, -1) 

Again, the x and the y values are flipped, meaning that this graph was flipped over the x-axis and y-axis, confirming our answer. 

Hope I helped :) 

I'm gonna say letter b
