Using Slopes to Classify Pairs of Lines Questions (3.5.3) – February 20, 2009 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Using Slopes to Classify Pairs of Lines Solutions (3.5.3) – February 20, 2009 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],The slopes are 3 and -⅓, which multiply to equal -1, or are called opposite reciprocals of each other. Therefore the lines are perpendicular lines. The slopes are 1 and -2, which do not multiply to equal -1 and they are not the same slope. Therefore the lines are not perpendicular lines, and they are not parallel lines. The slopes are 2 and 2, which means they have the same slope. Therefore the lines are parallel lines.
