Answer:
D. (0, 0), (0,3), (-3, 3), (-3, 0).
Step-by-step 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 [tex]\left[\begin{array}{ccc}-1&0\\0&1\end{array}\right][/tex] we create a reflection image in the y-axis.
So the result is letter D. (0, 0), (0,3), (-3, 3), (-3, 0).
