3-11.

On graph paper, graph $ΔABC$ with vertices $A(-2,7)$, $B(-5,8)$, and $C(-3,1)$. 3-11 HW eTool (Desmos). Homework Help ✎

1. Reflect $ΔABC$ across the x-axis to form $ΔA^{\prime}B^{\prime}C^{\prime}$. Name the coordinates of each new vertex.

2. Now rotate $ΔA^{\prime}B^{\prime}C^{\prime}$ from part (a) $180°$ about the origin (0, 0) to form $ΔA^{\prime \prime}B^{\prime \prime}C^{\prime \prime}$. Name the coordinates of each new vertex.

3. Describe a single transformation that would map $ΔABC$ onto $ΔA^{\prime \prime}B^{\prime \prime}C^{\prime \prime}$.
