This packet helps students understand the relationship between perpendicular and parallel lines. It includes problems ranging from graphing lines on a coordinate plane and seeing if they are parallel or perpendicular to looking at different equations of a line and determining whether or not they are perpendicular or parallel. Each page starts with easier problems that get more difficult as students work through the packet. After doing all 28 problems, students should be more comfortable doing these problems and have a clear understanding of how to solve them.
