I’m not sure what you’re options are but an equation in Y=mx+b form for this would be y= -3/2x + 5 
M is always the slope 
B is always the y intercept
        
             
        
        
        
It's C. When you're dividing g(x) by f(x), you get the equations in both B. and C., but C is more correct because you can't have x=-1/3 because the function is undefined at that number (you can't have the denominator equal 0)
