Translations
Triangle ABC is to be translated 3 units to the left and 5 units up.
It means all of the coordinates of its vertices are translated by the same amount.
The coordinates of A are (2,-2).
If we translate 3 units to the left we must subtract 3 to the x-coordinate
If we translate 5 units up we must add 5 to the y-coordinate.
Thus, the coordinates of A' are (2-3,-2+5) = (-1,3)
A' = (-1,3)
