Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.
The outlined content above was added from outside of Formative.

What is the equation for the translation of y = |x| 9 units up?
You may check your response using Desmos.
y = |x| - 9
y = |x + 9|
y = |x| + 9
y = |x - 9|
