It’s January 18, 2015. The morning of the Carlsbad Tri-City Half Marathon. The day I find out where my finishing time will be located on the inverse variation graph representing 13.1 = rt.
I’m ready. My ipod is charged. I’m wearing my favorite running gear, my mid race Larabar is packed and Uptown Funk is playing on my ipod.
I’m looking at:

Analyzing the Graph
Do you see the blue dot? It’s animated!! It actually moves to show all my possible times. Knowing my running speed, I predict that I’ll finish in between Marge’s and Jennifer B’s time. Check out Jennifer’s blog runningwiththegirls.com
Since I didn’t know how to create the animation, I contacted my colleague, J.J. Martinez for assistance. Using the Desmos Graphing Program, he wrote a list of commands to instruct the blue dot to trace the graph in between Marge’s and Jennifer’s time.
