Answer:
It is proportional
Step-by-step explanation:
To determine if its proportional/non-proportional is by using ratios
so go line by line
p pine and k oak
12 pine to 44 oak
18 pine to 66 oak
24 pine to 88 oak
30 pine to 110 oak
Start with the first line
p= pine per k= oak
so obviously not numbers but to help mind you it just means the numbers will be put as p/k (to make life simpler)
Or pine over oak
Second Line
12/44 which reduces down to 3/11
Third Line
18/66 which reduces down to 3/11
Fourth line
24/88 which reduces down to 3/11
Fifth line
30/110 which reduces down to 3/11
In order to be proportional the ratios all have to be equivalent to each other
Therefore,
3/11 = 3/11 = 3/11 = 3/11
So this is proportional
