Aline is drawn through (–4, 3) and (4, 3). which describes whether or not the line represents a direct variation? the line represents a direct variation because   -4\3 =4\3the line represents a direct variation because it is horizontal. the line does not represent a direct variation because it does not go through the origin. the line does not represent a direct variation because –4(3) ≠  4(3).
