ANSWER

The pairs that represent vertices from these options are:

• (-7, -3)

• (7, -3)

,

• (12, -10)

EXPLANATION

The rule for the translation 6 units right is:

[tex](x,y)\rightarrow(x+6,y)[/tex]

So after the translation the vertices are:

[tex]\begin{gathered} P(-3,7)\rightarrow(3,7) \\ Q(4,12)\rightarrow(10,12) \\ R(4,-2)\rightarrow(10,-2) \\ S(-3,-7)\rightarrow(3,-7) \end{gathered}[/tex]

Then, the rule for a 90º clockwise rotation about the origin is:

[tex](x,y)\rightarrow(y,-x)[/tex]

So, after the rotation, the vertices are:

[tex]\begin{gathered} (3,7)\rightarrow P^{\prime}(7,-3) \\ (10,12)\rightarrow Q^{\prime}(12,-10) \\ (10,-2)\rightarrow R^{\prime}(-2,-10) \\ (3,-7)\rightarrow S^{\prime}(-7,-3) \end{gathered}[/tex]
