Here where you label the y and slope
 
        
        
        
Answer:
x = 1, y = 1
Step-by-step explanation:
Use system of equations to solve for x and y by using substitution
 
        
                    
             
        
        
        
Answer:
28.56/linear yard
32.2256/linear meter
121.77984k
Step-by-step explanation:
a) Scale = k9.52*3 = 28.56/linear yard
b) Scale = k9.52*3.28 = 32.2256/linear meter
c) Cost = 3.9 * 32.2256 = 121.77984k
 
        
             
        
        
        
You can write it as a proportion and then solve the proportion. 
(2.5 hours is 150 minutes)
14 cars          x cars
--------------- = -------------------
45 minutes    150 minutes
Then solve.
x=46.6666666
So that is about 47 cars
        
             
        
        
        
Because it is 5 units to the left of 3 on a horizontal number line
