OLga [1]

Answer:

Option D.

Step-by-step explanation:

It is given that triangle XYZ has vertices X(–1, –3), Y(0, 0), and Z(1, –3).

Malik rotated the triangle 90° clockwise about the origin. So, rule of rotation is

(x,y)\to (y,-x)

Now,

X(-1,-3)\to X'(-3,-(-1))=X'(-3,1)

Y(0,0)\to Y'(0,0)

Z(1,-3)\to Z'(-3,-(1))=Z'(-3,-1)

The image points are X’(–3, 1), Y’(0, 0), Z’(–3, –1).

Therefore, the correct option is D.
