Chapter 9, Problem 11STP

To determine

To write the translation vector to describe the Regina’s route.

Answer to Problem 11STP

  $(x,y)\to (x-3,y+5)$

Explanation of Solution

Given:

Regina travelled $3$ blocks west and $5$ blocks north.

Calculation:

Let us consider the direction similar to map where north is positive y-axis, east is positive x-axis, west is negative x-axis and south is negative y-axis.

Therefore the translation vector will be as follows-

  $(x,y)\to (x-3,y+5)$
