2. How can you isolate the variable in this equation? -2n= 12 A. Add 2to 12
B. Add 2to both sides.
C. Divide both sides by 2.
D. Divide both sides by -2.

D

Step-by-step explanation:

-2/-2 = 1

2 negatives make a positive.

  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.
