    Answer:

    (0, 4) (-4, 3) (-4, 4)

    Step-by-step explanation:

    Translation rules:

    Units UP – Add to the y-coordinate.

    Units DOWN – Subtract from the y-coordinate.

    Units RIGHT – Add to the x-coordinate.

    Units LEFT – Subtract from the x-coordinate.

    ————————————————————————————————————–

    In this case, the word problem is asking for the points after a translation of 3 units up.

    (x, y+3)

    (0,1) → (0,4)

    (4,0) → (4,3)

    (4,1) → (4,4)

    ————————————————————————————————————–Now it’s time to reflect the new points over the y-axis.

    When reflecting over the y-axis, the y-coordinate remains the same, but the x-coordinate becomes the opposite value. (-x, y)

    (0,4) → (0,4)

    (4,3) → (-4,3)

    (4,4) → (-4,4)
