check the picture below.
so, y = -3 is simply a horizontal line, as you see there, and any perpendicular line to that will be a vertical one, whose slope is undefined.
we can check by simply picking two points off the red line hmmm say (-2,2) and (-2, -2)

Answer:
B
Step-by-step explanation:
-36-8= -36+(-8)
Answer:
To me it seems like 30
Step-by-step explanation:
I think it would just be 8 or 8.00
Answer:
The vertex is (2, 3)
Step-by-step explanation:
This is because the parent equation for problems like these is y=a(x-h)2 +k. The vertex is found through (h, k) and so with 2 as H and 3 as K, the vertex is (2,3).
