L = (P - 2W) / 2

Step-by-step explanation:

P = 2L + 2W

P = 2L + 2W - 2W

P - 2W = 2L

(P - 2W) / 2 = 2L / 2

(P - 2W) / 2 = L

L = (P - 2W) / 2

  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.
