Answer:
(12,0), (3, -1) (0,-4/3)
Step-by-step explanation:
To do this problem, you have to plug in the x and y values. For example, the first one would be 12-9(0)=12, and so on.
 
        
             
        
        
        
To find new price after discount we are going to find 10% of $13,999.00, then subtract the discount amount from $13,999.00. 
13,999.00 × ¹⁰/₁₀₀ = $1,399.90
13,999.00 - 1,399.90 = $12,599.10 
Therefore, new price = $12,599.10
        
             
        
        
        
The number could be anything because whatever it is it can be quadrupled
