l1: 7y = 9 can be rearranged to y = 9/7
l2: y = 4
Since the slopes of both lines are different (l1 has a slope of 0 and l2 has a slope of 1), the lines are not parallel.
Since the product of the slopes is not -1, the lines are not perpendicular.
Therefore, the lines are neither parallel nor perpendicular.
