1) The document announces that students have no assignment for Thanksgiving break and can sign up for extra credit on Test #4. 2) It provides instructions on how to plot points on a coordinate plane by explaining that the first number indicates movement left or right on the x-axis and the second number indicates movement up or down on the y-axis. 3) It gives examples of plotting the points (3,4), (2, -3), (-1, 2), and (0, -4) on a coordinate plane. It also gives an example of plotting the points (2, 2), (2, -1), (-1, -1), and (-1, 2), connecting them
