We checked the weekend's homework, a photocopy on solving systems by graphing.  Tonight's homework is for students to take the one (x,y) ordered pair solution for each system of linear equations, and substitute the x- and y-values back into each sentence to verify that the sentence is true.  I modeled two examples of how to do this in class, and this is Lesson 8-1 if you wish to reference the textbook resources.
