Answer:
The largest value in this situation would be $25+$50x6 which equals $450
 
        
                    
             
        
        
        
What you want to do, is isolate the y by itself to rewrite the equation as y=mx+b. So when you move the 5x over the equation looks like this -6y=-5x+30. Then you divide the -5x+30 by -6 to isolate the y. Thus making the equation y=5/6x-5. And since there is only one answer with the y-intercept as (0,-5); The answer is A.
        
             
        
        
        
5 because if you multiply the previous value by 5, you get the next answer
        
             
        
        
        
all have to do is divide the fraction to make it into a decimal , 
 6/8= 0.75
