Will give brainliestt which equation represents a line that is perpendicular to the line graphed? a) y = 3 b) x = 1 c) y = -3 d) y = 3x + 1

just sum

10 + 10 = 20

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
