Answer:
   the third one
Step-by-step explanation:
x^2 is always non-negative, so -3x^2 will always be non-positive. You can eliminate any tables with positive values for y.
 
        
             
        
        
        
Y=mx+b is the slope intercept form where m=slope and b=y intercept
so 
2y=x-4
divide both sides by 2
y=1/2x-2
slope is 1/2
        
                    
             
        
        
        
Answer:
<h3>
           - 14</h3>
Step-by-step explanation:
{x -  some integer}
2x  -  the first even integer
2x+2  -  the second consecutive even integer 
2x+4  -  the third consecutive even integer (the largest)
2x + 2x+2 + 2x+4  - the sum of three consecutive even integers
2x + 2x+2 + 2x+4 = -48
    6x + 6  = -48
         ÷3         ÷3
     2x + 2 = -16
          +2      +2
      2x+4 = -14
