Basically just substitute
3(-2)-1-3(-2) = -6-1+6 = -1
The answer is -1.

Answer:
x=21/5
Step-by-step explanation:
5x:9 = 7:3 
Turn the ratios into fractions: 
5x/9 = 7/3 
Then cross mutiply 
15x=63 
x=21/5
 
        
             
        
        
        
A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
