And this one too please.

(x, y) --> (x, y-4)

Step-by-step explanation:

Just look at one point to determine the translations ex. K

Original coordinate of K: (0, -1)

Translated coordinate: (0, -5)

Between the two x coordinates, 0 and 0, nothing changes, so x --> x

The y coordinate goes from -1 to -5. 4 is being subtracted

(to technically figure out that it's -4, you can do -1 + n = -5, then solve for n by adding one to both sides, and getting n = -4. You add n, because that represents the translation that's happening to the coordinate)

y --> y - 4

(x, y) --> (x, y - 4)
