Exploring Linear Equations and the Cartesian Plane
Introduction
What is y=mx+b? And ax+by=c? Looks like Greek to me! And no, it's not the Pythagorean Theorem again. Actually, you are looking at two formulas developed by the French mathematician Rene Descartes. These are two of the most famous formulas in all of Algebra. These algebraic formulas represent ALL straight lines that can be graphed on the coordinate plane.
This project is designed to help you figure out what all those variables and formulas mean - through exploration and visiting various information sources on the web. This webquest will help you make sense of the all those letters, lines, and graphs in Algebra.
Linear Equations, like the two found at the beginning, are the basis for all slopes, maps, business models, and relationships between data sets. Learning these formulas is the next step after you have a solid understanding of the Cartesian plane.
Remember that in high school, we study curved lines and parabolas, like those found when kicking a soccer ball or a rocket ship blasting off. But before we can make sense of the more complicated lines we first need to study straight lines. This is a unit based on the Slope-Intercept Form - the part of algebra that explores Linear Equations and how they relate to Rene Descartes and the coordinate plane.
The purpose of this Webquest is NOT just to give you a lot of work for two weeks. The purpose is for you to gain new understanding of some of the most difficult concepts in algebra... slope and linear equations!
Have fun, do your best, and enjoy the journey.
