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.
F
We are given a rectangle EFGH.
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 4 units down. Therefore, we will subtract 4 from the y-coordinate of each vertex.
| Vertices of EFGH | (x,y-4) | Vertices of E'F'G'H' |
|---|---|---|
| E(1,3) | (1,3 - 4) | E'(1,- 1) |
| F(4,3) | (4,3 - 4) | F'(4,- 1) |
| G(4,1) | (4,1 - 4) | G'(4,- 3) |
| H(1,1) | (1,1 - 4) | H'(1,- 3) |
