Answer:
4/9, or 0.4∞
but 0.4∞ has a repeating decimal, so the expanded form is ∞ also
 
        
             
        
        
        
Answer:
1. y=3/2x + 12   2. y= 1/4x + 8
Step-by-step explanation:
Use the slope formula to get the slope for each line.  Then plug either of the x and y coordinates into the formula y= mx + b and also plug in the slope that you just found and solve for b. 
 
        
             
        
        
        
Answer:
The slope is m=2
Step-by-step explanation:
7 - 3 = 4 in y
2 - 0 in x
4/2
Simplify
2/1 or 2
