Question Analysis
This question tests the student's ability to find the axis of symmetry of a parabola given two symmetric points with the same y-coordinate.

Key Concept Explanation
The axis of symmetry of a parabola is the vertical line that divides the parabola into two mirror images. If two points on the parabola have the same y-coordinate, their x-coordinates can be used to find the axis of symmetry using the formula .

Step-by-step Solution
1. Identify the x-coordinates of the given points: and
