2-132.

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?

What do you notice about the opposite sides?

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

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?

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