Exercise 20 Page 576

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.

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 segment 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 segment after a translation of 1 unit to the right and 3 units up. Therefore, we will add 1 to the x-coordinate and add 3 to the y-coordinate of each vertex.

Vertices of XY (x+1,y+3) Vertices of X'Y'
X(1,1) (1 + 1,1 + 3) X'(2,4)
Y(- 2, - 3) (- 2 + 1,- 3 + 3) Y'(- 1,0)

Let's do the translation!
