First, i put the equation in y=mx+b by dividing 2, since its 2y. since it’s perpendicular we’re talking about you switch the sides (opposite reciprocals). the rest should be self explanatory.
 
        
        
        
The fraction Is already in its simplest form :) 
They do not have any common factors

The product is
(-d)^2 -4^2 = d^2 -16 . . . . . corresponds to the 2nd selection
        
             
        
        
        
Y= -1/4x + 5/4 
because -1/4 is the slope and 5/4 is the y intercept
