I think the answer is C. (a.k.a the third one)
I hoped this helped !!
Y/x=k
when y=9, then x= -3
9/-3=-3
⇒ k= -3
Step-by-step explanation:
Given the information:
- 1st square: 12 square units
- 2nd square: DOUBLE that of the first square = 2*12 = 24 square units
From that, we can determine the length of the side in each square:
1/ 
<=> x = 2
2/ 
<=> a = 2
Please have a look at the attached photo.
Hope it will find you well.
