Slopes of Parallel and Perpendicular Lines: An Inquiry-Based Exploration

This is an inquiry-based learning activity used to teach students of the properties of the slopes of parallel lines and the slopes of perpendicular lines. This activity is best used before going too in-depth with the algebraic properties of parallel and perpendicular lines as it allows students to discover, on their own terms, these properties. The papers are arranged so that you may print the graphing activities on one sheet of paper and the questions on another. Have students put papers side by side so they can easily look between their graphing work and the questions, in order to better discover the answer to each question, Please leave me any feedback on the product.
