What is a (teacher checked image)
A coordinate starts in quadrant 4 and is translated (-x,y). What quadrant is the coordinate in now?

The rule (x,y) -> (-x,-y) means.
What is change the signs of both x and y.
A shape has coordinates A(2,4) ,B(4,4), C(5,5), D(3,7), E(-1,7). It has been translated to coordinates A'(0,5), B'(2,5), C'(3,6), D'(1,6),E'(-3,8). Are the shapes congruent? If not why not?
No, The translation rule is (x,y)---> (x-2,y+1) coordinates D' does not follow that rule.
Which rotation does not flip the x and y coordinates?
What is a 180 degree rotation.
