You can try then by plotting the points in. 
The answer is C
Make sure by plotting in the points, lets take (-5,27)
y = 12 -3(-5)
y = 12 + 15
y = 27
27 = 27
This is correct 
Lets try (-1,15)
y = 12 -3(-1)
y = 12 + 3 
y = 15 
15 = 15
This is correct 
Lets try (8,-12)
y = 12 -3(8)
y = 12 - 24 
y = -12 
-12 = -12
This is correct too. 
The correct ordered pairs are <span>C(-5,27),(-1,15),(8,-12)</span>
        
             
        
        
        
2/3 could equal 4/6 , 6/9, 8/12 , 10/15 , 12/18 ETC
