Answer:
(x, y) ⇒ (½x, ½y)
(x, y) ⇒ (x + 7, y + 7)
Step-by-step explanation:
each x value of P'Q'R' is half of the x value for PQR
each y value of P'Q'R' is half of the y value for PQR
each x value of P"Q"R" is seven units to the right of the x value for P'Q'R'
each y value of P"Q"R" is seven units above the y value for P'Q'R'
