Hi,
 parallel (lines slant in same direction):Slopes identical
perpendicular: Slopes are negative reciprocals of one another
Neither: slopes do not satisfy either of the above:
4x+8y=16  OR y = (-1/2)x + 2    m = -1/2
3x+6y=7   OR y = (-1/2)x + 7/6  m = -1/2
These lines are Parallel, their slopes are identical
