6-16.

On graph paper, graph $ΔABC$ if $A(−2,7),$ $B(−5,8),$ and $C(−3,1)$. .

1. Reflect $ΔABC$ across the $x$ -axis to form $ΔA'B'C'$. Name the coordinates of each new vertex.

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

3. Describe a single transformation that would change $ΔABC$ to $ΔA''B''C''$.
