We continued reviewing the point slope equation of the line today and then covered our final topic of the unit.  We took a look at how to determine if a line is perpendicular or parallel to another line.  We used the slope intercept form of the line to determine this.  If the slope is the same, then the lines are parallel.  If the slopes are negative reciprocals of each other, then the lines are perpendicular.  We went over 3-4 examples together in class before the students then got started on their assignment.
