Matt spent 3/10 of his allowance on projects, 2/5 on snacks, and 2/3 of the remainder on books. What is the fraction of his allowance was spent on books?

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
