6x-2. Which can be simplified to (3x-1) by taking a common factor, 2.
We can see that the only change that occurs to the points after the reflection is that the x-values are negated, because -4 becomes 4 and -6 becomes 6. And the only reflection that causes only a negation in the x-values is a reflection over the x-axis.
Hope this helps
