Exercise 3 Page 549

Horizontal translations affect the x-coordinate, and vertical translations affect the y-coordinate.

T_(<-12, 4>)(H)

Practice makes perfect
To write a rule for the translation, we should remember that horizontal translations affect the x-coordinate, and vertical translations affect the y-coordinate. Keeping this in mind, let's consider the given translation.

12 units left and 4 units up Since the point moves 12 units left and 4 units up, we will subtract 12 from the x-coordinate, and add 4 to the y- coordinate. With this, we can write the rule, as shown below. (x - 12,y+4) → T_(< -12, 4>)(H)
