The equation that represents a proportional relationship is:
y = 32x
Because:
y/x = 32
So that implies that y is directly proportional to x.
Note that other equations represent a proportional relationship in some form, only that the relationship y = 32x is the only direct proportional relationship.

Answer:
3 centimeters
Step-by-step explanation:
given ratio is
18 km : 1 cm
Now if km is multiplied by 3, the cm should also be multiplied by 3.
=> 18 x 3 : 1 x 3
=> 54 km : 3 cm
 
        
                    
             
        
        
        
Answer:
y=x-2
Step-by-step explanation:
If you have drawn the graph of  .
.
To determine the equation of the line which  should be drawn to solve the equation:  x² - 4x +3=0
Simply carry out the subtraction: 

The equation of the line which should be drawn is: y=x-2
What this means is simply:
If
