Answer:
A
Step-by-step explanation:
You are going to divide 4 from both sides of the equation. This gives you 3x+1=2x . (Because 8/4=2)
 
        
                    
             
        
        
        
To find the y-intercept of the equation, we will put 0 in for x, and find y. 
So, y = 14.2 - 3.9(0)
y = 14.2
        
             
        
        
        
X, y - the numbers

The two numbers are 37 and 21.
 
        
        
        
A is at (2,-2). after 90 degree counter clockwise, it is at (2,2).  Then, a transformation one unit to the left gets it to A', (1,2)
