A map of the town that Hannah lives in can be represented by the Cartesian plane. Hannah starts off at $(-4, 9)$ and walks 10 units to the left and 7 units down to get to her new location. Along what line could she have walked to get to the new location directly from her old location? Express your answer in the form $ax+by=c$ where $c$ is a positive integer and $a$ and $b$ are integers not having any common factors other than 1.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

i know the point slope is y= 1/11x-46/11

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.

the answer is -81 is the answer
