To describe the route taken by the limousine based on the given transformations, let's analyze the two transformations \( T_{(-15,3)} \) and \( T_{(21,-2)} \).

  1. Starting Position: The limousine starts at the coordinates \( (-15, 3) \).

  2. First Transformation: The move to \( (-15, 3) \) shows the limousine is beginning at these coordinates.

  3. Second Transformation: The new position after the second transformation is \( (21, -2) \).

Now, let's calculate the movement in the x-direction (east-west) and y-direction (north-south):

X-axis Movement:

  • Starting x-coordinate: \(-15\)
  • Ending x-coordinate: \(21\)
  • Movement in the x-direction: \( 21 - (-15) = 21 + 15 = 36\)
  • Since the movement is positive, the limousine moves east.

Y-axis Movement:

  • Starting y-coordinate: \(3\)
  • Ending y-coordinate: \(-2\)
  • Movement in the y-direction: \(-2 - 3 = -5\)
  • Since the movement is negative, the limousine moves south.

Summary of the Route:

  • The limousine drives 36 block(s) east,
  • then it drives 5 block(s) south.

Final Text Describing the Route:

The limousine drives 36 block(s) east and 5 block(s) south.
