14. GROUP ACTIVITY 2. Connect the points in alphabetical order then connect the last letter to the first letter. What figure do the points make? A(-6,1) B(-6,3) E(0,3) F(2, 5) 1. Make a Cartesian plane on a manila paper. Use your 1x1 pictures to plot the following points: (note: each member must answer one item only) 3. How can you relate the points being connected and the figure to how a group must work? C(-4,5) D(-2, 5) G(4,5) H(6,3) I(6,1) J(0,-5)
