A) Translation will slide all the points using the vector - add the vector to each point...
P’(3, 7), Q’(7, 6), R’(8, 2), S’(4, 3)

B) Rotation is tricky. 90 degrees will swap x with y and counterclockwise will reverse the sign of the new x
P’(-7, 3), Q’(-6, 7), R’(-2, 8), S’(-3, 4)

A clockwise rotation would swap the values and reverse the sign of the new y values
Half turn rotation would just reverse the values of all the coordinates
