1. A room is 12'8" long. It has a door at one e
mis 12'8" long. It has a door at one end that is 4'6" wide. How much space
is left on this wall?
a. 8'2"
C. 17'4"
b. 7'9"
d. 8'11"

question:

could we have options?

"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.
