Which rule describes the composition of transformations that maps JKL to J”K”L”

Answer:
C) Rotate Counter clockwise 90º and Translate (x-2,y)
Step-by-step explanation:
1) Rotating counterclockwise 90º the [tex]\bigtriangleup JKL \Rightarrow J'(2,-4), K(5,-4), \:L(2,-2)[/tex]
Rotating counterclockwise 90º rule is: [tex](-y,x)[/tex]
We'll twist the values:
[tex]\bigtriangleup J'K'L' \Rightarrow J(4,2) K(4,5), L(2,2)[/tex]
Check the picture below.
2) Now we need to translate ΔJ'K'L' following this rule [tex](x-2,y)[/tex]
to have ΔJ''K''L''
[tex]\bigtriangleup J''K''L'' \Rightarrow J''(0,2), K''(2,5), \:L''(2,2)[/tex]
