Equations of Straight Lines UBC Calculus Online Course Notes A Review of Lines and Slopes This page serves as a quick review of straight lines and their important features. Many of these features are fundamental to a mathematical understanding of Calculus. After all, the branch of Calculus we will first explore (the part involving derivatives) is the study of how a curve can be approximated (at least in a very local sense) by a straight line (the tangent line). Thus, before we can discuss such concepts effectively, we must understand the idea of slopes and lines very, very well. The reason we are interested in straight lines is that they are so simple; we need to know only two pieces of information to describe a line completely. Which two pieces of information are used depend on the situation, but several different possibilities lead to the same description of a particular line. We will explore these details below as we discuss The slope of a straight line How to describe a straight line Because this is a review, most students can skim this material, making sure that they
