Question

what is the result of a horizontal translation of a point (x, y) by h units? (x, y) → (-x, y) (x, y) → (x+h, y) (x, y) → (x, -y) (x, y) → (x, y+k)

Explanation:

In a horizontal translation, only the x - coordinate of a point changes. If we translate a point (x, y) horizontally by h units, we add h to the x - coordinate when h>0 (right - ward translation) or subtract h from the x - coordinate when h < 0 (left - ward translation). The y - coordinate remains the same.

Answer:

B. (x, y) → (x + h, y)
