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 point D after translation is 1.

Step-by-step explanation:

If the coordinates of the point D' are (x, y), then, after translation, it will be

D(x + 6, y - 4).

that is 6 units right and 4 units down

It is given that the point before translation is D'(3, 5).

So, x + 6 = 3 + 6 = 9 and

y - 4 = 5 - 4 = 1

So, the y coordinate of point D after translation is 1.

he sells x mount because thats eqivilqant to the maz and then divided into quarters
