What is the y-coordinate of point D after a translation of (x, y) → (x + 6, y – 4)?

D′(3.5,
)

The y - coordinate of D after a translation is 1

Explanation:

The point D after a translation is given by

The y - coordinate of the point D is 5.

Now, we shall determine the value of the y - coordinate of D after the translation

Let us consider the y - coordinate of D' and D

Thus, we have,

Subtracting both sides by 4, we get,

Thus, the y - coordinate of D after a translation is 1
