Answer:
(0, 1)
(-1, -1)
(1,3)
Step-by-step explanation:
Given the function;
y = 2x + 1
when x = 0
y = 2(0)+1
y = 1
Hence the required pair is (0, 1)
when x = -1
y = 2(-1) + 1
y = -2 + 1
y = -1
Hence the coordinate is (-1, -1)
when x = 1
y = 2(1) + 1
y = 2 + 1
y =3 
Hence the coordinate is (1, 3)
 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
In the inequality, you want to simplify it to get x on one side, and the numeric values on the other. 
So, moving 9 to the other side, you get, 8x<-32
Then, you can divide by 8 on both sides to get x alone. 
You get, x<-4. 
From this, we can see that it should be an open dot at -4, and pointing to the left. 
So, the correct number line is A.
 
        
             
        
        
        
(3x + 1/2 ) + ( 7x - 4 1/2 ) 
3x+7x + 1/2 - 4 1/2
10x -4
