    no i have to fine the slope and it ended up as -6/0 and then the second part of question was to write an equation with perpendicular slope

    The slope of a vertical line is undefined i.e x/0. Now if your are told to find or write the equation of a line perpendicular to it, then you simply have to remember one thing. Slopes of perpendicular lines are negative reciprocals of each other and vertical lines and horizontal lines are perpendicular to each other.Thus in this case the slope of the horizontal line would be simple 0

    a horizontal line is perpendicular to a vertical line. a horizontal line has slope 0

    notice that the rule -1/m works for m= -6/0 you get 0/6 = 0 for the slope of the perpendicular line

    vertical line -6/0-------->negative ricprocal for perpindcular line---->0/6 or 0
