Given the coordinates of the vertices of a pre-image figure, describe how to find the coordinates of the image vertices if the figure is translated vertically.

Step-by-step

Step 1:

find out the amount and direction of the vertical translation.

+3 means translating 3 units up, and -6 means translating 6 units down.

Step 2:

to each of the coordinate pairs, add the value of the translation to the y-coordinate (i.e. the second number of the pair).

For example, if the translation is +3, and if one of the vertices is (4,1), then the image of the vertex is (4,1+3) = (4,4).

Repeat for the rest of the vertices.

Step 3:

Check by graphing both image and preimage to see if the shapes are identical.  If not, look for a mistake in the translation process.

i would but where it is?
