Look at the coefficient of x (the slope).
Is -2 positive or negative?
Since -2 is negative, The slope is negative.
        
             
        
        
        
Answer:
y=1/3x-1/3
Step-by-step explanation:
 
        
             
        
        
        
The line is called the directrix.  Here we have a vertical directrix, so a parabola sideways from usual.
Geometry is best done with squared distances.  The squared distance from an arbitrary point (x,y) to the vertical line x=2 is 

We equate that to the squared distance of (x,y) to the focus (-2,0): 



We could call that done.  A more standard form might be
 
 
        
        
        
False. A reflection over the y-axis would result in: (-8,5)
