Triangle PQR has vertices cap p times open paren negative 2 comma 6 close paren , cap q times open paren negative 8 comma 4 close paren , and cap r times open paren 1 comma negative 2 close paren It is translated according to the rule open paren x comma y close paren rightarrow open paren x minus 2 comma y minus 16 close paren What is the y -coordinate of cap p prime ?
The translation rule changes each point’s y-coordinate by subtracting 16. Point P has y-coordinate 6, so P′ has y-coordinate 6 − 16 = −10. Therefore, the correct choice is negative 10.
