Does anyone know this answer???

the pitch of the roof is 24ft²

Step-by-step explanation:

Formula: 1/2(b×h)

Given: b=4, h=12

> 1/2(4×12)

> 1/2(48)

> 24

  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.
