Quadrilateral defg has vertices d(−2,4) , e(4,7) , f(10,3) , and g(8,0) . what are the coordinates of d′e′f′g′ after quadrilateral defg has undergone a rotation 270° counterclockwise about the origin? enter your answers, as ordered pairs (x, y) , in the boxes.

A rotation 270° counterclockwise about the origin is the same as rotation 90° clockwise about the origin and has a rule:

(x,y)→(y,-x).

Then:

the coordinates of vertices of quadrilateral D′E′F′G′ are D'(4,2), E'(7,-4), F'(3,-10), G'(0,-8).

constants mean the stopped points or the points on a graph that nothing is changing, hope this
