Answer:
2/1 or 2
Step-by-step explanation:
if you find a spot were the line is line up with the boxes in the graph like at (-2,0) up 2 and right one you will see the line is lined up again and since slope is rise/run its 2/1 or 2
 
        
             
        
        
        
D has the commutative property because it just flip flopped the numbers.

Answer:

Step-by-step explanation:
The axis of symmetry can be calculated using the formula: 

First we must determine a and b from the quadratic:  . This is in standard form, with the highest power first in descending order.
. This is in standard form, with the highest power first in descending order. 
Standard form is also: 
If we compare this to the quadratic given, we can conclude that: 

Substitute the values for a and b into the formula. 

Multiply in the denominator. 

Divide. 

This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
