Answer:
A" (-4, -7); B" (-5, -4); C" (-4, -3); D" (-3, -4)
Step-by-step explanation:
It says in the problem that polygon ABCD is translated (x - 2, y + 3), right? So we translate each point by subtracting 2 from the x-coordinates of A, B, C and D to get A', B', C' and D'. From A', B', C' and D', we rotate by 90 degrees by using the format (-y, x). The x-coordinates of A', B', C' and D' remain constant but become the new y-coordinates and the y-coordinates of A', B', C' and D' become negative and the x-coordinates for A", B", C" and D".
