Question 800748

      (x,y) --> (x+7,y-9)

Just substitute the first coordinate for x and
substitute the second coordinate for y and then simplify: 


        (x,y) = (x+7,y-9)

a. P(0,0) --> (0+7,0-9) = (7,-9)
b. Q(-2,1) --> (-2+7,-2-9) = (5,-11)
c. R(-7,-1) --> (-7+7,-1-9) = (0,-10)
d. S(7,14) --> (7+7,14-9) = (14,5)
