Erties of Transformations
In the pre-image of the parallelogram, the slope of AD is
-3 and the slope of BC is -3. The image is translated
down 7 units and then reflected over the y-axis.
The slope of A"D" is
The slope of B"C" is
What can you determine about the line segments A"D"
and B"C"?

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
