Exercise 11 Page 458

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.

B

Practice makes perfect

Let's start by considering the given triangle.

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 right and 3 units up. Therefore, we will add 4 to the x-coordinate and add 3 to the y-coordinate of each vertex.

Vertices of PQR (x+4,y+3) Vertices of P'Q'R'
P(- 2,3) (- 2 + 4,3 + 3) P'(2, 6)
Q(4,2) (4 + 4, 2 + 3) Q'(8,5)
R(3,- 3) (3 + 4,- 3 + 3) R'(7, 0)
Let's do the translation!

The coordinates of R' are (7,0). Therefore, the correct option is B.
