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.

How is the graph of y = |x| - 8 different from the graph of y = |x|?

How is it the same?

After responding, you may check your answer using Desmos below. If you must edit your response, consider also editing your note card.

10 pts

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|
