Exercise 17 Page 516

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.

Graph:

Vertices: C'(1,2), D'(3,- 2),

Practice makes perfect

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

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 of 3 units to the right and 2 units down. Therefore, we will add 3 to the x-coordinate and subtract 2 from the y-coordinate of each vertex.

Vertices of CD (x+3,y-2) Vertices of C'D'
C(- 2,4) (- 2 + 3,4 - 2) C'(1,2)
D(0,0) (0 + 3,0 - 2) D'(3,- 2)

Let's do the translation!
