The only whole numbers that multiply together to equal 22 are 1 x 22, and 2 x 11.
Unfortunately, neither of these pairs add OR subtract to equal 11. 
        
             
        
        
        
(1/2)x+b=y because the equation that given the slope is 1/2 if you leave y alone and take the x’s number 
put the point now , 4+b=3 so b is -1 
the equation is (1/2)x-1=y
        
             
        
        
        
Answer:
Cost function = 40a + 500
Cost of 90 articles = $4,100
Step-by-step explanation:
The fixed cost is $500 and it will.not change regardless of production level. 
The Variable cost is $40 and increases by every additional unit produced. 
Assume the number of articles produced is a. 
Cost function would be: 
Total cost = Variable cost * Number of articles + Fixed cost 
TC = 40a + 500
Using this, the cost of 90 articles is:
= 40 * 90 + 500
= $4,100
