Translating the triangle DEF involves moving the triangle along the coordinate plane
The y-coordinate of point D after the translation (x, y) → (x + 6, y – 4) is 1
How to determine the y-coordinate of D'?
From the figure the coordinate of D is:
D = (-2.5,5)
The rule of translation is given as:
(x, y) → (x + 6, y – 4)
So, we have:
(x, y) → (-2.5 + 6, 5 – 4)
Evaluate the sum and the difference
(x, y) → (3.5, 1)
Remove the x-coordinate
y → 1
Hence, the y-coordinate of point D after the translation is 1
