Working on solving systems of linear inequalities? This matching activity is great for students who are practicing graphing systems of linear inequalities. With 6 practice problems (written in various forms) that match to one of the 12 answers students have to graph the inequality to compare answers. This activity works best when page 2 is printed on translucent paper so students can line up their sketch below the answer options. The graphs are the same sizes so the will lay atop one another. The students final answer spells out the riddle question "this is light as a feather, yet no man can hold it for long. What am I?" - the answer is your "BREATH".
