Answer:
See below 
Step-by-step explanation:
The first two questions are slope = 0 
    a horizontal line has zero slope   
             slope = rise/run  = 0 / run = 0 
Greatest y value is + 4   from x = 3 to 4 
the least y value is -3 fro x = -4 to -3 
 
        
                    
             
        
        
        
Answer:
   C.  11
Step-by-step explanation:
Substituting, we have ...
   8{80, 19, 11} ?= 88
   {640, 152, 88} ?= 88
The value from the set that makes the equation true is x = 11.
_____
<em>Alternate methods of solution (other than substitution)</em>
It can be easier to make use of your knowledge of factoring:
   8x = 8·11
   x = 11
Or to make use of your knowledge of numbers (place value):
   8·10 = 80
so x will not be very different from 10.
