Question

1. Polygon L'U'M'B'E'R'J'A'C'K' is the image of polygon LUMBERJACK after a translation (x,y) - (x + 12, y +8). LU' 4 M K! ID C ATTE R' 23 2 -2 -3 - - . D Part A: What are the orlginal coordinates of each point of polygon LUMBERJACK? L U M B E R J А C R Part B: Show the translation on the coordinate plane above.

Answer 1

Ok, what whe have to do in order to find the original coordinates of each letter is substract 12 from all x components and substract 8 from all y components:

L' (5, 13) => L (-7, 5)

U' (6, 13) => U (-6, 5)

M' (8, 11) =>M (-4, 3)

B' (8, 9) =>B (-4, 1)

E' (6, 7) =>E (-6, -1)

R' (6, 2) =>R (-6, -6)

J' (5, 2) =>J (-7, -6)

A' (5, 7) =>A (-7, -1)

C' (3, 9) =>C (-9, 1)

K' (3, 11) =>K (-9, 3)

The original coordinates of the L'U'M'B'E'R'J'A'C'K' before the translation are the ones found on LUMBERJACK.
