Question 708269
No matter where a point is on this line,
it always sees {{{ y = 8 }}} because it is 
horizontal. At the given point. it sees
{{{ y = 8 }}} and {{{ x = 5 }}}.
-----------------------
But if {{{ x = 1049137 }}}, or any other number,
{{{ y = 8 }}} still.
So the equation for this line is {{{ y = 8 }}}
