The translation of a point involves shifting the point from one position to another. The y-coordinate of D after (x, y) → (x + 6, y – 4) translation is 1.
See attachment for ΔDEF
From the attached figure, we have:
D = (-2.5, 5)
Given that:
(x, y) → (x + 6, y – 4)
Substitute -2.5 for x and 5 for y on the right-hand side.
(x, y) → (-2.5 + 6, 5 – 4)
(x, y) → (3.5, 1)
The y-coordinate of D after (x, y) → (x + 6, y – 4) translation is 1.
