Dear Accelerated Analytic Geometry Student, This is a fast-paced, college preparatory math course. It emphasizes more complex applications and challenging exercises than might be encountered in the traditional high school course. Your success in this class will be the result of the consistency of your study and homework habits. Reviewing class notes each night and diligent homework efforts will greatly enhance your learning process. You are a student whose job and responsibility is to be the best student that you can be! During the semester, we will be learning many new concepts in Accelerated Analytical Geometry. Because of the pace and rigor of the course, there will not be a lot of time to spend reviewing topics that you were exposed to in Accelerated Coordinate Algebra or previous math courses. This packet is a review of those topics and courses. Work all of the problems neatly on notebook paper, numbering your work, and CIRCLING your answers. Be sure to make a note of the problems that you have difficulty solving. For the graphing problems, you may use graphing paper or make your own sketch on notebook paper. You must show your work for problems in the review packet. Do not list only an answer. The completed packet represents your first graded assignment in Accelerated Math II and is due on the first day of school, August 1, 2015, to Mrs. Dedman in Room 4020. I look forward to working with each of you this next school year. Sincerely, Mrs. Dedman Accelerated Analytic Geometry teacher Accelerated Geometry Summer Work Packet Find the slope, x-intercept and y-intercept for each line and the graph each line. 2. y 2 x 3. x y 4 6. 3 x 2y 0 Write an equation for each line in slope-intercept form. 7. 8. 1. y x2 4. x y 5 5. 2x 3y 12 9.
