An achitect is drafting the scale model of Andrew's living room on a computer program which involves coordinate planes. To occupy a bigger dining table, he changes the location and size of the dining table whose coordinates are (2, 4), (6,4), (2,-2), and (6,-2), by reflecting it across the y-axis and then dilating. The new coordinates of the dining table are (-9, 6), (-3, 6). (-9, -3), and (-3,-3).
unit in the scale model represents 1 feet.
