This file contains two different resources. The first is a file that I complete with the students just to review the skills of graphing in slope intercept form and writing and equation given a graph and also given the slope and a point. There is a review sheet for the students to practice by them selves as well as an answer key to the practice.
I currently use this as review for my high school students before beginning my piece wise function unit but it could easily be used for younger grades as well.
Please let me know if you have any questions.
