In this lesson, students continue their work with parametric equations to see the relationship between their work with functions and vectors (N-VM.C.11).
This lesson continues the work of understanding the definition of a vector. The main question of this lesson is whether the image of a line under a linear transformation is again a line. Before answering this, the process of finding parametric equations for a line in ℝ 2 and ℝ 3 introduced in Lesson 21 needs to be extended.
