Answer:
it’s not proportional 
Step-by-step explanation:
the number that you are always multiplying should be constant
2x9 = 18 but 4x9 does not equal 20 
 
        
             
        
        
        
 In this case, the graph should be shown as linear since the order is only 1. solving the two equations, the answer is x is 4.5 liters fruit syrup and y is 2.5 liters water.
        
                    
             
        
        
        
Answer: (24,-9)
(0,9)
(4,6)
Step-by-step explanation:
3x + 4y = 36
Using (3,-2) will be:
= 3(3) + 4(-2)
= 9 - 8 = 1
Using (1,7) will be
= 3(1) + 4(7)
= 3 + 28 = 31
Using (0,0) equals to 0
Using (24,-9) will be:
= 3(24) +4( -9)
= 72 - 36 = 36
Using (0,9) will be:
= 3(0) + 4(9) 
= 0 + 36 = 36
Using (4,6) will be:
3(4) + 4(6)
= 12 + 24
= 36
Using (-12,18) will be:
= 3(-12) + 4(-18)
= -36 - 72
= -108
The correct options are (24,-9), (0,9 and (4,6)
 
        
             
        
        
        
It would be y=4x-2 because:
8x-3y=6-4x
-8x         -8x
-3y=6-12x
/-3  /-3 /-3
y=-2+4x
y=4x-2
