Question

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

Answer 1

The y - coordinate of D after a translation is 1

Explanation:

The point D after a translation is given by $(x, y) \rightarrow(x+6, y-4)$

The y - coordinate of the point D is 5.

Now, we shall determine the value of the y - coordinate of D after the translation $(x, y) \rightarrow(x+6, y-4)$

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

Thus, we have,

$y-4=5$

Subtracting both sides by 4, we get,

$y=1$

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