Question

select the transformation needed to match the shaded pre - image to the dashed image. you can use only one transformation. pre - image → image (target) history (select a row to review) original position

Explanation:

Step1: Observe the pre - image and image

The pre - image is below the x - axis and to the right of the y - axis, and the image is above the x - axis and to the right of the y - axis. The shape and orientation are the same, just the vertical position has changed.

Step2: Determine the transformation

Since the only change is in the vertical position, and there is no reflection, rotation or dilation, it is a vertical translation. Count the number of units from a corresponding point of the pre - image to the image. For example, point A of the pre - image at (3, - 5) and point A' of the image at (3, 4). The vertical distance is \(4-(-5)=9\) units.

Answer:

Vertical translation 9 units
