Question

SUPER POINTS! HURRY FOR BRAINLIEST

Answer 1

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.)
