Math6-8
Parallel and Perpendicular Lines Practice Set
By Bradley S.
A two-section review problem set for 8th graders that practices writing linear equations from slope and point information, with two problems of each type. Section one covers parallel and perpendicular lines; section two covers writing equations from various given information, all in slope-intercept form, with worked examples and space to show work.

Teacher Guide & Tips
- Use as a review block before a quiz or unit test, either as a 40 to 50 minute independent practice set or as a homework assignment with a short debrief.
- Discussion question: How can you tell from two slopes alone whether lines are parallel, perpendicular, or neither, and why does the product of perpendicular slopes equal -1?
- Scaffold for struggling readers: Have them complete the worked example together first, then use the point-slope form step by step before solving for y.
- Extension for advanced students: Ask them to write the equation of a line perpendicular to a given line through a point, then verify it by checking that the two lines intersect at a right angle using the slopes.
- Estimated time: about 5 minutes per problem, roughly 35 to 45 minutes total for all problems.
