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 [tex]$(x, y) \rightarrow(x+6, y-4)$[/tex]
The y - coordinate of the point D is 5.
Now, we shall determine the value of the y - coordinate of D after the translation [tex]$(x, y) \rightarrow(x+6, y-4)$[/tex]
Let us consider the y - coordinate of D' and D
Thus, we have,
[tex]y-4=5[/tex]
Subtracting both sides by 4, we get,
[tex]y=1[/tex]
Thus, the y - coordinate of D after a translation is 1
