A statement is something you are standing for and your sticking to it.
        
                    
             
        
        
        
Answer:
P(-1, 0); Q(0, -1); R(2, -1). 
Step-by-step explanation:
When you reflect coordinates over the y-axis, the y-coordinates do not change, while the signs of the x-coordinates are flipped. You can see the example attached!
And so, after reflecting P'(1, 0), you would get P(-1, 0) because the sign of the x-value is flipped and the y-value does not change.
Q'(0, -1) becomes Q(0, -1) because 0 is neither negative nor positive, and the y-value does not change. 
R'(-2, -1) becomes R(2, -1) because the sign of the x-value is flipped to positive and the y-value does not change. 
Hope this helps!
