Step-by-step explanation:
The coordinates of WXYZ:
W(3,-5) X(1,-1), Y(-1,-5) and Z(1,-7)
plotting the points:
Rotating the figure 90 degrees counterclockwise:
from (x, y) to (-y, x)
The new coordinates after rotation:
W' = (-(-5), 3) = (5, 3)
X' = (-(-1), 1) = (1, 1)
Y' = (-(-5), -1) = (5, -1)
Z' = (-(-7), 1) = (7, 1)
Plotting the coordinates:
