Explanation:
#"the equation "y=-8#
#"is a horizontal line parallel to the x-axis and passing"#
#"through all points in the plane with a y-coordinate of "-8#
#"since it is parallel to the x-axis it's slope "=0#
#"a line perpendicular to it would therefore be a vertical"#
#"line parallel to the y-axis"#
#"with undefined slope"#
