Module Overview
Lines

Wood running parallel with some boards highlights in bright redLine segments in a coordinate plane can be analyzed by using characteristics of the line. In this module, you will explore slope, length, and midpoint. In your mathematical courses, understanding these attributes plays a key role in direct applications as well as coordinate proofs. In addition, these concepts are essential in professions such as carpentry, architecture, and engineering, as well as in athletic and recreational activities where distance and location play important roles, such as hiking, boating, or baseball.
