Name: ________________________ Advisory Book #: _______ ALGEBRA II If you are taking BOTH Geometry AND Algebra II in the fall of 2015, you will only need to complete the Geometry summer project this year. Due Wednesday September 16th Name: ________________________ Advisory Book #: _______ Part I: Demonstrating Knowledge of Slope and Linear Equations Given the information in each problem, write the equation for the line described. Show your work and write your final answer in the box provided. A. Slope intercept form (y = mx + b) through the points (2, 4) and (0, 2). B. Standard form (Ax + By = C) for a line parallel to the line y = 2x + 5 through the point (5, 0). C. Slope intercept form for a line perpendicular to the line 2x + y = 4 and passing through the point (1, 1). D. Slopeintercept form of a line parallel to the line x – 4y = 12 with an yintercept of 3. Name: ________________________ Advisory Book #: _______ Part II: Graphing Data by Plotting Points All measurements given in centimeters. On the grid on the next page, plot the data from both tables on a single graph. Make sure to label and scale the axes. Plot the points from each table in a different color (ie Table 1 = red, and Table 2 = blue) and include a sketched line of best fit.
