Question 1040225
Say you are on this line. You move along the line and
all you see is {{{ x=3 }}}, so no matter what {{{ y }}} is,
you only see one value of {{{ x }}}.
-----------------------------
The only line that satisfies this is a vertical line through
the point ( 3,0 ) 
All the other points are ( 3,y ) where {{{ y }}} could be anything
like even 11.00040371999 or {{{ pi }}}
