On graph paper, graph $\Delta ABC$ if $A(–4, 3), B(–6, 1),$ and $C(–8, 5)$.   

1. Rotate $\Delta ABC \:90º$ clockwise (↻) about the origin to form $\Delta A^{\prime} B^\prime C^\prime$. What are the coordinates of $A^\prime$?

2. Apply the function $(x, y) \rightarrow (x + 5, y + 1)$ to translate $\Delta A^{\prime} B^\prime C^\prime$. What are the new coordinates of point $C^{\prime \prime}$? If you need help remembering this notation, refer to your work from problem

• Hint (b):

  Make sure you are translating $\Delta A^{\prime} B^\prime C^\prime$ obtained from part (a).
