2-77.

Use the graph to find the coordinates of Points *A*, *B*, and *C*. Then multiply each value by −2. For example, Point *A* is originally (−3,2). It's new coordinate will be (6,−4). Find Points *B* and *C*.

After multiplying each *x*-coordinate and *y*-coordinate by −2, plot the new points.

Its sides are twice as long and rotated 180 degrees.
