This lesson was an introduction to graphing parallel and perpendicular lines in a 9th grade Algebra I class. The main focus of the lesson was that parallel lines have the same slope and perpendicular lines's slopes have opposite reciprocals. The standard this lesson fell under was SCCCR A1.AREI.3: Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
