In this lesson, students have the opportunity to attend to precision in thinking and language (MP6) as they determine what information is needed to graph a line and ask precise questions to elicit that information. Then, they apply concepts of parallel and perpendicular lines to conclude that if two lines are both perpendicular to the same line, they must be parallel.
- Determine what information is needed to write the equation of a line and ask (orally) questions to elicit that information.
- Let’s work with both parallel and perpendicular lines.
- I can gather information about a line and write its equation.
