To describe the route of the limousine and the rigid motions represented by the transformations \( T_{23,3} \) and \( T_{-17,-7} \):

  1. The transformation \( T_{23,3} \) indicates that the limousine moves 23 blocks to the east (as it is positive in the x-direction) and 3 blocks to the north (as it is positive in the y-direction).
  2. The transformation \( T_{-17,-7} \) indicates that the limousine then moves 17 blocks to the west (since it is negative in the x-direction) and 7 blocks to the south (as it is negative in the y-direction).

Now, we can summarize the route in words:

First, the limousine drives 23 blocks east and 3 blocks north, and then it drives 17 blocks west and 7 blocks south.
