X
When I divide my number by 3 and subtract four, I get
six. What is my number?

your number is 30

Step-by-step explanation:

x ÷ 3 - 4 = 6

x = 30

30

is the answer

  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.
