On graph paper, graph $ΔABC$ with vertices $A(-2,7)$, $B(-5,8)$, and $C(-3,1)$.

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) $180^\circ$ about the origin $\left(0, 0\right)$ 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 $ΔA^{\prime \prime}B^{\prime \prime}C^{\prime \prime}$.
