D. because you just count 7 units to the right and then 2 units up.
I hope this helps you
R. (g+s)=g.s
R.g+R.s=g.s
g.s-R.g=R.s
g (s-R)=R.s
g=R.s/(s-R)
Answer: I'd say it's not proportional.
Explanation: Y is 9 times X which is true for;

2 * 9 = 18
3 * 9 = 27
However, 4 * 9 = 36 not 40. Therefore, the propotion chain is broken here.
