There are 4 quadrants in a coordinate plane The starting point is in the second quadrant, while the finishing point is in the fourth quadrant. The starting point is a reflection of the checkpoint across the y-axis Part A The points are given as: For the starting point, the x-coordinate is negative, while the y-coordinate is positive. This implies that the starting point is in the second quadrant For the finishing point, the x-coordinate is positive, while the y-coordinate is negative. This implies that the finishing point is in the fourth quadrant Part B The checking point is given as: The starting point is given as: Notice that the y-coordinate of both points are the same, but the x-coordinates are negated. This means that the starting point is a reflection of the checkpoint across the y-axis, and vice versa
