How do you find the coordinates of a point after translation?

• To find the new coordinates after translation, multiply the original coordinates by the translation values.

• To find the new coordinates after translation, subtract the translation values from the original coordinates.

• To find the new coordinates after translation, add the translation values to the original coordinates.

• To find the new coordinates after translation, divide the original coordinates by the translation values.
