Question

Find the image of triangle GHJ under the translation of (x, y) --> (x - 1, y - 8).
A. triangle NPQ
B. triangle DEF
C. triangle ABC
D. triangle KLM

Answer 1

OK this is easy. Like, easy-peasy-easy. We know that the new triangle should have its distance 1 less than the original triangle (in X direction), and 8 less than the original (in Y direction). Subtract to find out. Example: The x co-ordinate of G is 2, so the x- co-ordinate of the new triangle must be one less....what is it and which is the only triangle with that answer as the x co-ordinate?

Answer 2

so the answer is D?

Answer 3

Yes!! Correct again!
