Answer:
The vertices of coordinates of image are Q'(0,-4), P'(-7,-6) and R'(-1,-2).
Step-by-step explanation:
The vertices of triangle QPR are Q(–4,0), P(–6, 7), and R(–2, 1). It is rotated 90° counterclockwise about the origin to form a new triangle Q'P'R'.
If a figure rotated 90° counterclockwise about the origin, then
The coordinated of image are
Therefore the vertices of coordinates of image are Q'(0,-4), P'(-7,-6) and R'(-1,-2).
