Exercise 14 Page 459

Translations are done by adding or subtracting values from the x-coordinate if the figure is being moved left or right, and from the y-coordinate if the figure is being moved up or down.

A'(- 5,3), B'(- 3,4), C'(2,2), D'(0,- 2)

Practice makes perfect

Let's start by plotting the given points and connecting them to draw our quadrilateral.

polygon

Translations are done by adding or subtracting values from the x-coordinate if the figure is being moved left or right, and from the y-coordinate if the figure is being moved up or down. We want to draw the image of our figure after a translation 4 units up. Therefore, we will add 4 to the y-coordinate of each vertex.

Vertices of ABCD (x,y+4) Vertices of A'B'C'D'
A(- 5,- 1) (- 5,- 1 + 4) A'(- 5,3)
B(- 3,0) (- 3,0 + 4) B'(- 3,4)
C(2,- 2) (2,- 2 + 4) C'(2,2)
D(0,- 6) (0,- 6 + 4) D'(0,- 2)
Let's do the translation!
