Find a coordinate rule for a reflection across the line y = 2x. Then use the rule to find the image of triangle ABC

= [ 2 6 0 ]

[ 3 -4 4 ].

Be sure to clearly show your work indicating how you found your rule. In addition write the coordinate matrix for triangle A'B'C'. Graph and label both the pre-image and the image triangle on graph paper.
