I'm sure @Compassionate can tell you, as I don't remember. However, for future reference, it's usually a good idea to post math questions in the math section.

Hi, my name is Compassionate. Nice to meet you! :)
A translation is a type of transformation that simply moves a figure from one location to another.
The translation rule will tell you how the image has moved. The rule (x, y) → (x + 1, y - 2) means all x-coordinates of the pre-image are moved 1 unit right while all y-coordinates are moved 2 units down to create the image.
Remember that a translation can also be seen as a function which is a type of input/output machine.
• If you had a point at (2, 3) and wanted to translate it using the rule (x+1, y-2), you first use the x-coordinate rule of x+1 as the input to find the output.
o →If 2 is placed in for x and then, by following the rule of x+1, add 1 to the x-coordinate, the output is 2+1 which equals 3.
o →If 3 is placed in for y and then, by following the rule of y-2, subtract 2 from the y-coordinate, the output is 3-2 which equals 1.
