Vertical compression of a function is moving the graph of the function towards the x axis. 
It is done by multiplying F(x) with IaI<1, the absolute value of a is less than 1. Then we get f(x)=a*F(x).
If we have a function F(x)=x, and we multiply it by a=1/2, we get:
f(x)=a*F(x)=a*x=(1/2)*x.
This linear function is vertically compressed because the the graph of a new function is closer to the x axis. 
        
                    
             
        
        
        
3/7. if you make them equivalent fractions it would be 30/70 or 14/70. 30/70 is bigger.

Answer:
2. 1/2
Step-by-step explanation:
slope is rise over run 
y2-y1/x2-x1
7-5/6-2 = 2/4 = 1/2
