Question 593647: I don't understand this, I'm very confused. Especially with this problem. I've been trying to complete it, but I can't seem to figure out the steps. If someone could explain this to me, that would be great!
Is the relationship b/w the values in both tables a direct variation, an inverse variation, or neither? Write and equation to model a direct or inverse variation.
TABLE 1
x | 2 | 4 | 6 | 8
y | 14 | 28 |42 | 56
TABLE 2
x | 2 | 4 | 8 | 12
y | 4 | 2 | 1 | 2/3

You can put this solution on YOUR website! TABLE 1
x | 2 | 4 | 6 | 8
y | 14 | 28 |42 | 56
This table is a direct variation (as x gets larger, y gets larger)
Its equation would be: y=7x
..
TABLE 2
x | 2 | 4 | 8 | 12
y | 4 | 2 | 1 | 2/3
This table is an inverse variation (as x gets larger, y gets smaller)
Its equation would be: y=8/x
