This document provides instructions for graphing linear equations. It begins with a "Do Now" activity to find and correct mistakes in a sample function table and graph. It then shows examples of graphing different linear equations by plotting points from their function tables on coordinate grids. The document concludes with a prompt to explain to an absent student how to determine from a graph if a mistake was made in a problem.
