This lesson develops a third way to understand an equation for a line in the coordinate plane. In previous lessons, students wrote an equation of a line by generalizing from repeated calculations using their understanding of similar triangles and slope. Let's see what happens to the equations of translated lines. Let's see what happens to the equations of translated lines.
