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.
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 5 units to the right and 1 unit up. So, we will add 5 to the x-coordinate and add 1 to the y-coordinate of each vertex.
| Vertices of ABC | (x+5,y+1) | Vertices of A'B'C' |
|---|---|---|
| A(- 1,- 2) | (- 1 + 5,- 2 + 1) | A'(4,- 1) |
| B(- 2,2) | (- 2 + 5,2 + 1) | B'(3,3) |
| C(- 3,0) | (- 3 + 5,0 + 1) | C'(2,1) |
