1. •The starting point will be located in quadrant Q
•The finishing point will be located in quadrant S
Explanation: the x and y values determine where the points are located on the graph
2. The starting point is (-5.4, 3) and the checkpoint is (5.4, 3). The difference is they’re both in different quadrants, and one has a negative value, and the other is positive. They are related because they’re all in one race, and the checkpoint will be involved in the race, most likely between the start and finish points, located in quadrant P.
I hope that helps, merry Christmas and happy holidays! :)
