Answer:

Translation Rule

Explanation:

The rule that describes a translation 3 units down is the following:

Translation Rule: (x, y) → (x, y - 3)

In this rule, (x, y) represents the coordinates of a point in the original position, and (x, y - 3) represents the coordinates of the translated point after moving 3 units downward.

For example, if we have a point A with coordinates (2, 5), applying the translation rule would give us the new coordinates for the translated point A':

A' = (2, 5 - 3) = (2, 2)

So, when a point is translated 3 units down using this rule, the y-coordinate of the original point is decreased by 3 to obtain the y-coordinate of the translated point. The x-coordinate remains the same.

It's important to note that the translation rule can be applied to any point, not just (2, 5). The key is to subtract 3 from the y-coordinate to move the point downward by 3 units.
