Example 5:  Find the equation of the axis of symmetry for each parabola.  

For each of the following, both points are located on the same parabola

a)  (3, 2)   and   (7,2)

b) (‐2, 5)  and   (6, 5)

c) (2,‐1) and (5, ‐1)

Page 369 - 370 #'s 3 - 7, 9, & 11

To determine the axis of symmetry with no vertex, take 2 x­values that have the same y­value, add them together and divide by 2.
