West of Checkpoint A, which is at (0,5), are two hurdles that Helena needs to jump over. Hurdle 1 is 4 units west of Checkpoint A, and hurdle 2 is 3 units west of hurdle 1. Checkpoint B is 2 units west of hurdle 2.
What are the coordinates of Checkpoint B? The answer needs to be in ordered pair form PLS. Thank you
