How do I find the equation of the axis of symmetry of a parabola that contains the points (-2,6), (0,-6), (6,6)

Did you make a sketch?

How do I find the equation of the axis of symmetry of a parabola
that contains the points (-2,6), (0,-6), (6,6)
Code:
                |   :
o    |   :        o
|   :
o   |   :       o
(-2,6)  |   :     (6,6)
|   :
----------+---:------------
o |   :     o
|   :
(0,-6)*   :   o
|   o

They made it very easy for us . . .

We know the axis of symmetry bisects the parabola.
Since (-2,6) and (6,6) are at the same height,
. . the axis is halfway between them.

Got it?
