1. Translations
Sign In
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.
G
Let's start by considering the given point.
Translations are done by adding or subtracting values from the x-coordinate if the point is being moved left or right, and from the y-coordinate if the point is being moved up or down. We want to draw the image of our point after a translation 4 units left and 3 units up. Therefore, we will subtract 4 from the x-coordinate and add 3 to the y-coordinate of the point.
Coordinates of A | (x-4,y+3) | Coordinates of A' |
---|---|---|
A(- 1,2) | (- 1 - 4,2 + 3) | A'(- 5,5) |
