Answer:
D. (0, 0), (0,3), (-3, 3), (-3, 0).
Explanation:
From the statement we know that the vertices of the triangle are:
(0,0) , (0, 3) , (3, 3) , (3, 0).
By multiplying the vertex matrix with the reflection matrix
we create a reflection image in the y-axis.
So the result is letter D. (0, 0), (0,3), (-3, 3), (-3, 0).
