5. The graph below shows Glenn’s distance from home as he rode his bicycle to school, which is just down his street. His next-door neighbor Pablo, who lives 100 m closer to the school, leaves his house at the same time as Glenn. He walks at a constant velocity and they both arrive at school at the same time.[br][br]a. Graph the linear function that represents Pablo's distance from Glenn's home as a function of time.
b. Estimate from the graph when the two boys will pass each other.
