What is the equation of the axis of symmetry of the graph with the order pairs of (-2,0) and (6,0).

How would I do this since? I thought perhaps I could do -2+__=6 which would be 8 then 8/2 =4 so x=4 my brother says I'm suppose to do 6-2=4/2=2 so x=2 who's right or are we both wrong.I've always been given an equation and then used -b/2a to find the vertex. I've searched and can't find any examples when given two x- intersects ordered pairs.

Half way between is x=2
