The top row is the x value, the bottom row are the Y values.
The first point (0,)) would remain the same.
The second point (0,-4) , the -4 moves the the x location and the sign reverses and the X value becomes the y value, so would become (4,0)
The third point the x value becomes the Y value and the Y value becomes the X value, so becomes (0,5)
To get 0,4,0 on the top and 0,0,5 on the bottom.
The answer is B.
32.
Reflecting on the Y, the X values change sign, the Y values stay the same.
First point (-2,0) becomes 2,0
2nd point -5,3 becomes 5,3
3rd point (0,5) becomes 0,5 ( it stays the same since Y = 0)
The answer is D.
33.
Subtract 2 from the X values and subtract 1 from the y values.
5,7 becomes 3,6
3,1 becomes 1,0
2,3 becomes 0,2
The answer is A.
