Is the relationship between the variables inthe table a direct variation, an inverse variation, both, or neither? If it is a direct or inverse variation write a function to model it
x: 2, 5, 12, 20
y: 30, 12, 5, 3

A. Direct variation: y = 15x
B. Inverse operation: y = 60/x
C. Direct variation: y = 2x + 2
D. Neither

I said neither because it doesn't seem to have a pattern at all.

1. As one increases, the other decreases. What does that tell you? Check by inserting x to find values of y

2. Oh so is y = 60/x correct?
Because 60/2 is 30, 60/5 is 12, 60/12 is 5, and 60/20 is 3
So that would fit x: 2, 5, 12, 20, y: 30, 12, 5, 3
