Final answer:
The coordinates of the preimage and image can be used to determine the line of reflection, which is the y-axis.
Step-by-step explanation:
The given algebraic description of the reflection of quadrilateral BYNR onto quadrilateral PMZT is (x-y) → (-x,y). To determine the line of reflection, we can compare the coordinates of the vertices of the preimage and the image. The x-coordinates of the vertices remain the same, while the y-coordinates change sign. This means the line of reflection is the y-axis.
