Consider the figures shown.

Consider the quadrilateral with vertices at A(3, -1), B(1, -8), C(5, -8) and D(7, -1), and the quadrilateral with vertices at A'(-3, -1), B'(-1, -8), C'(-5, -8) and D'(-7, -1).

Consider the transformation from $\left(x,y\right)$(`x`,`y`) to $\left(x-3,y-8\right)$(`x`−3,`y`−8).
