Find slope : 
---------------------------------------------

When the slope is 0, the graph is a horizontal line. 
Equation of the graph is y = -4
------------------------------------------------------
Answer: y = -4------------------------------------------------------
 
        
        
        
First, change the fractions to a common denominator, which is 21. 
so 3/7 * 3/3  = 9/21
1/3 * 7/7 = 7/21
Add the two together
9/21 + 7/21 = 16/21
Then take 21/21 - 16/21 = 5/21
There is 5/21 of the pizza left.

Answer:
Step-by-step explanation:
The vertex would be the highest/lowest point so lets factor this first
when we factor we get
2(x^2+6x+8)
2(x+4) (x+2)
Using zero product property we find the 2 x values and x intercepts are 
-4 and -2
the middle point of these points is -3 
Substitute -3 for x and solve
2(-3+4) (-3+2)
2 * 1 *  -1 
2*-1
-2
(-3,-2) is the vertex
