Chapter 7

Coordinate Geometry

A typical Math 2 test has about six coordinate geometry questions. But that’s counting just the
questions that are primarily about coordinate geometry. A lot of trigonometry and functions
questions assume an understanding of coordinate geometry. In fact, the material in this chapter is
relevant to approximately 30 percent of Math 2 questions.
