**Problem:**How do you determine the line of symmetry of a reciprocal equation?

**Solution:**

For example, I'll graph the reciprocal function Y=1/(x+2)

^Just a quick sketch

And the equation of the line of symmetry is simply -(x+2), which can be seen here:

^Also a quick sketch

By adding a negative in front of any reciprocal equation, you have the line of symmetry. That much I figured out.

**The Real Problem:**Why does this happen? I mean, how can I explain it in plain english?
