Answer:
A
Step-by-step explanation:
x | y
0 0
1 4
2 n -> 8
3 12
I've rewritten the x-y table so it's easier to read.
Take a point: 2,8. 2 times 4 is 8.
Take another point: 3,12. 3 times 4 is 12.
Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is y=kx, where k is the constant of proportionality. So the equation is y=4x. This means x and y are directly proportional.
(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)
