please solve. you have to draw your own polygon p, there is no reference

3. For the polygon P with vertices: (2,-2), (6,-4) (4,-6), (2,-4) and the transformation T: Rotate 240 clockwise about the point (-2,1). a. Find a matrix for the transformation T. Justify your reasoning and show work. You can use a calculator for any matrix products, and give your answer either in exact form or in decimal form to 2 places. b. Find the images of the vertices of the polygon P using your matrix. c. Draw a graph of P and its image. You can do this either by hand or using a tool such as Geogebra
