Question

hello everyone! Can anybody help me out with this problem? I don't need a big explanation just the answer and a brief explanation on how you got it :)

Answer 1

Given the table between (x) and (y)

The constant of variation (k) is given by:

`k=(y)/(x)`

As shown, from the table

When x= -2, y = -4

`k=(-4)/(-2)=2`

when x = 1, y = 2

`k=(2)/(1)=2`

when x = 6, y = 12

`k=(12)/(6)=2`

so, the answer will be k = 2
