-----------------Let's find the missing number for the pair (0, ?)--------------------
x-3y=9 Start with the given equation


1%280%29-3y=9 Plug in x=0

%2B0-3y=9 Multiply

-3y=9 Combine like terms on the left side


y=%289%29%2F%28-3%29 Divide both sides by -3 to isolate y



y=-3 Divide




So the ordered pair is (0,-3)


-----------------Let's find the missing number for the pair (12, ?)--------------------
x-3y=9 Start with the given equation


1%2812%29-3y=9 Plug in x=12

%2B12-3y=9 Multiply

-3y=9-12Subtract 12 from both sides


-3y=-3 Combine like terms on the right side


y=%28-3%29%2F%28-3%29 Divide both sides by -3 to isolate y



y=1 Divide




So the ordered pair is (12,1)



-----------------Let's find the missing number for the pair (?, 0)--------------------


x-3y=9 Start with the given equation


1x-3%280%29=9 Plug in y=0

1x%2B0=9 Multiply

x=9-0Subtract 0 from both sides


x=9 Combine like terms on the right side




So the ordered pair is (9,0)



-----------------Let's find the missing number for the pair (?, -2)--------------------


x-3y=9 Start with the given equation


1x-3%28-2%29=9 Plug in y=-2

1x%2B6=9 Multiply

x=9-6Subtract 6 from both sides


x=3 Combine like terms on the right side




So the ordered pair is (3,-2)




--------------------------------
Answer:
So the ordered pairs are:

(0,-3), (12,1), (9,0) and (3,-2)
