If the lines are parallel, their slopes are the same.  If they are perpendicular, the slope of one line is the negative reciprocal of the slope of the other line.  You should know how to find the slopes.  Find them and compare them.

A more perfect statement (includes cases of vertical lines, which have undefined slope) is
 
two lines are parallel if they have identical slopes (including 'undefined')
 
two lines are perpendicular if both have a defined slope and their product equals -1, or if one line is horizontal and the other is vertical.
