Let’s see what happens to the equations of translated lines.
Unit 3 ● Lesson 8
We will be able to explain where to find the slope and vertical intercept in both an equation and its graph so that we can write equations of lines using y=mx+b.

8.3 Activity: Translating a Line
I can write equations of lines using y=mx+b
Student volunteer: Place point A in three different locations above and/or below the x-axis to translate the existing line. For each location, the class will write the equation of the line and the coordinates of point A.
