For examples #1-4, visually find the line of reflection and write its equation in the space provided. After, confirm your answer by doing the following:[br][br][list=1][*]Use the line tool to construct the line of reflection on the graph[/*][*]Use the polygon tool to trace over the pre-image[/*][*]Use the reflection tool to reflect your polygon over the line[/*][/list][br]After, complete the table provided and write a coordinate rule for the reflection.

Write a coordinate rule for this transformation.
[math]\left(x,y\right)\rightarrow\left(y,x\right)[/math]
Write down this rule in your notebook. You're going to need it for homework and future assessments!
