- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.

What you'll learn
- Write the equation of the line through a given point parallel or perpendicular to a given line, using equal slopes for parallel and the negative reciprocal for perpendicular
- Explain the perpendicular relationship $m_1 m_2 = -1$ from a quarter-turn rotation, state its precondition, and explain why a horizontal and a vertical line are perpendicular although their slope product is not $-1$
- Classify a pair of linear equations given in mixed forms as parallel, perpendicular, neither, or the same line written two ways
- Use a parallel or perpendicular condition to solve for an unknown coefficient and to find the perpendicular bisector of a segment
