Remember that x-coordinates determine how far left or right the point is, and the greater the x-coordinate, the further to the right the point is.
With y-coordinates, they determine how far up or down the point is, and the greater the y-coordinate, the further up the point is.
Now, we see that the x-coordinate is being increased by 2 and the y-coordinate is being decreased by 4. Using what we know, this rule represents a translation of 2 units to the right and 4 units down.
