I still dont understand

1. c

2. a

3. d

4. b

Step-by-step explanation:

1. Rotation of 270° counter clockwise around the origin transforms point (x, y) into (y, -x). Therefore, R(4, -3) -> R'(-3, -4)

(Note: given the options, I think there is a mistype in questions 2 and 3)

2. Reflection over x-axis transforms point (x, y) into (x, -y). Therefore, R(3, -4) -> R'(3, 4)

3. Translation 13 units up transforms point (x, y) into (x, y+13). Therefore, R(3, -4) -> R'(3, -4+13) = R'(3, 9)

4. The answer must be option b because it is the only one that includes 4 coordinates.

There is one true solution, with a value greater than 6.
