Solve this equation :
12 - y = -15

y= 27

Step-by-step explanation:

12-y= -15

subtract 12 from both sides

12-12. -15-12

-y= -27

divide both sides by -y (or -1)

-y÷ -y. -27÷ -y

y= 27

for the points

step-by-step explanation:

  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.
