Draw a coordinate grid, 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 do you notice about the opposite sides?

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

   Hint (b):

   Remember that reflect means to 'flip.' If you were to flip the quadrilateral across the $x$-axis, where would each point end up? Plot points $A'$, $B'$, $C'$, and $D'$ below (the $x$-axis) to where you think they should end up.

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