The axis of symmetry of a parabola is the vertical line passing through its vertex. Given a parabola
, the vertex x-coordinate can be found using

In your case, the formula leads to

So, this parabola is symmetric with respect to the line 
Answer:
( B) explination
Step-by-step explanation:
6:38 so i got to a easy number to just add easier
+0.22
7:00. -9:45=2.45 so 45 is 3/4 of an hour so there is 1 left so 15=1/4 of an hour so 2.45
+0.15
3:00
so 22-15=7 so she drove 3 hours and 7 minutes :)
If I'm right, then the answer would be B. 800. Hope I helped!
Y-(-7)=-9(x-6)
Y+7= -9x+54
Subtract 7 from both sides
Y= -9x+47
