Answer 1

Answer:1

Step-by-step explanation:3/3=1

Answer 2

Yes, it shows direct variation

Explanation:

Given

The above table

Required

Is it a direct variation?

The constant of variation (k) is:

`k = y/x`

For each pair x and y, we have:

`k = 5/15 = 1/3`

`k = 6/18 = 1/3`

`k =9/27 = 1/3`

Since the calculate constant have the same value for all pair or x and y, then the table shows direct variation
