Answer:
D. 4 units to the right (positive x direction)
Step-by-step explanation:
we only need to look at the change of one point like A (-1, 4).
the translation does
(-1, 4) becomes (3, 4)
so, what happened here ?
y staid the same, but x increased by 4.
as only x changes it can be only a shift along the x-axis, and that means left or right (y is up and down).
and when x increases, that means we are moving in the positive direction, and that means to the right.
therefore, D is the right answer.
