Answer:
Step-by-step explanation:
4(0) + 3y=12
4x0=0
0+3y=12
3 x 4=12
y=4
 
        
             
        
        
        
Well to begin, you'll need a graph but you have to do:
y2-y1
---------
x2-x1
(Which is the average rate of change formula.)
In order to find your "y" you look for your x on the graph the move either direction until you touch the graph. Hope this helps.. :)

Part A: Let x and y be the number of persons attending the two-day conference and y be the number of vouchers released. The equation that would best express the given is,
                                             y = 4x
Part B: The number of people attending the conference is determined by dividing the given number of vouchers by 4. The answer is 956.
