Students use list operations to perform reflections, rotations, translations and dilations on a figure, and graph the resulting image using a scatter plot.
Students use the List Editor to enter values that gives the x- and y-values for a figure that is being rotated and reflected about the y-axis. They enter = –L1 and = –L2 in the formula bar of list 3 to create L3, the opposite of each of the x-values in L1. Then do a similar process for the y-values in L2.
Students create a scatter plot with connected points using the combinations of lists. For each combination, students determine what type of reflection or rotation occurred.
Students will translate a figure by manipulating formulas to translate the x- and y-values.
