The graph shows a journey in a car. Which of the statements most likely describes the journey at the portion of the graph labeled N? A line graph is drawn on the first quadrant of a coordinate plane. The x-axis is labeled Time in seconds, and the y-axis is labeled Distance in miles. The line graph is divided into 7 segments labeled I, J, K, L, M, N, and O. I starts at the origin and is a straight line slanting up. J is a line segment that starts at the end of I and is horizontal. K is a curve that starts at the end of J and curves up. L is a straight line that starts at the end of K and is horizontal. M is a straight line that starts at the end of L and slopes down. N is a straight line that starts at the end of M and is horizontal. O is a curve that starts at the end of N and curves down to finally touch the x-axis. The car continues its journey, because the portion shows a linear function. The car is waiting at the starting point, because the portion shows a constant function. The car stops at a distance away from the starting point on its return journey, because the portion shows a constant function away from the starting point. The car is traveling the same distance per unit of time on its return journey, because the portion shows a linear, increasing function away from the starting point.
