The equation is $x = 2$

#### Explanation:

The line you are asked to find (also called axis of symetry) must divide both bases in half, so to calculate its equation you have to find the $x$ coordinate of the midpoint of any base.

If you take the upper base you get:

${x}_{M} = \frac{- 2 + 6}{2}$

${x}_{M} = \frac{4}{2}$

${x}_{M} = 2$

So the line's equation is: $x = 2$
