Draw a coordinate graph, and then plot and connect the following points: A$(−3,1)$, B$(−1,3)$, C$(4,2)$, D$(2,0)$.  

1. What is the shape you created?

   Hint (a):

   What is this shape?
   Notice that the shape has two pairs of parallel sides.

2. Reflect the shape across the $x$-axis. List the coordinates of the new points.

3. Multiply each coordinate of the original shape by $3$. Graph the dilated shape. What are the new coordinates of the points?

   Hint (c):

   Multiply each coordinate of the original shape by three.

   Use eTool below to plot the points, and complete the rest of the problem.
