An equivalent expression would be 2x+4
        
             
        
        
        
Answer:
4 1/2
Step-by-step explanation:
 
        
             
        
        
        
You have to solve for y
Subtract 2x to the other side
Divide both sides by 4
y=-1x/2-2
Graph D has a slope of -1/2 and a y-intercept of -2
