Why are lines parallel?

Unit 3: Linear Functions
Lesson 6 of 20

Objective: SWBAT change from standard form to slope intercept form, explain the reasoning of why lines are parallel, and write the equation of a line going through a point and parallel to a given line.

Big Idea: The emphasis in this lesson is that students not only know the definition of parallel lines, but why lines are parallel.
