Exercise 13 Page 550

Add or subtract the necessary values to the x- and y-coordinates to find the new points.

Practice makes perfect

Let's begin by identifying the vertices of the given polygon.

We are asked to translate the given polygon using a translation written in function notation.

T_(⟨ 3, 2⟩)(x,y) This means we should add 3 to each x-coordinate and 2 to each y-coordinate of all of the vertices.

(x,y)	(x+ 3,y+ 2)	(x',y')
(- 9,3)	(- 9+ 3,3+ 2)	(- 6,5)
(- 6,- 1)	(- 6+ 3,- 1+ 2)	(- 3,1)
(- 1,2)	(- 1+ 3,2+ 2)	(2,4)

With these points, we are able to draw transformed polygon.
