A Master's Degree project designed to provide an understanding of the graphing of linear equations at the Algebra 1 level. Use Java applets to learn about ordered pairs, graphing equations, horizontal lines, vertical lines, slope, equations and slope, finding the equation of line, scatter plots, parallel lines, perpendicular lines, and solving a system. Also included are quizzes and tests; Ask the Teacher (email a question); a discussion room, glossary, index, and message board; a crossword puzzle and word search; and an Internet project predicting the number of people who will vote in the year 2004. The site also provides a simple scientific calculator, and GraphIt, a plotter that can graph functions, differentials, and integrals to help with algebra, trigonometry, and calculus homework.
