Answer: C. 
Step-by-step explanation:
1. You have the following equation of the parabola in Vertex form:

Where h is the x-coordinate of the vextex and k is the y-coordinate of the vextex.
2. You know that the vertex of this parabola is at (-2, 5), then, susbtitute this point into the equation. Then, you obtain:

3. Therefore, the answer is the option C.
it should be B
if i’m wrong please correct me
Set the equation equal to y
Add x to each side
7y=14 +x
Divide each side by 7
y=2 + x
The slope is whatever number corresponds with the variable x
In this case there is no number in front of the x which indicates that the slope is 1
I had this question before. The answer is 128 :)
I believe it's the first one, if a = b, then b = a.
