Exercise 3 Page 472

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:

polygon

Vertices: A'(0,1), B'(1,- 3), C'(- 2,- 2)

Practice makes perfect

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

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 left and 4 units down. Therefore, we will subtract 3 from the x-coordinate and subtract 4 from the y-coordinate of each vertex.

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