The graph shows the distance a cyclist traveled in yards (y) as a function of time in seconds (x). The graph is divided into four segments; labeled P, Q, R, and S, respectively. 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 yards. The line graph is divided into 4 segments labeled P, Q, R, and S. P starts at the origin and is a straight line slanting up. Q is a line segment that starts at the end of P and is horizontal. R is a straight line that starts at the end of Q and slants up with a steeper slope than P. S is a straight line that starts at the end of R and slopes down to touch the x-axis.
