Answer: 10 and 11 or -11 and -10
 
        
                    
             
        
        
        
Replace x in the equation with the given x values and solve for y:
3 + 2(4) = 11
3 + 2(5) = 13
3 + 2(9) = 21
3 + 2(10) = 23
the y values are: 11, 13, 21, 23
 
        
                    
             
        
        
        
Answer: an infinity many solutions
Step-by-step explanation:
If a system has infinitely many solutions, then the lines overlap at every point. In other words, they're the same exact line! This means that any point on the line is a solution to the system.
