Answer:
Yes it is
Step-by-step explanation:
y=-9x means that for every x value, the y value decreases by 9, so it is proportional because the value of y decreases the same amount each time. For example, if x=1, y=-9. If x=5, y=-45, and so on.

i think
2 y squared minus 3 x minus 4 8 x squared
I think the answer is ribosomes.
